My wife and I recently traveled to Grand Sirenis Riviera Maya with another couple for our first trip to Mexico. Not being familiar with Mexico we relied on traveler reviews and advice from our travel agent and decided on Grand Sirenis. Reviews can only tell you so much and it will eventually come down to your own experience, and let me tell you our experience was wonderful. For those concerned about H1N1 everything was fine. Proper precautions were taken from the airport to the resort, and all was well. To get to Grand Sirenis you must fly into Cancun and take a shuttle to the resort. If you have the option of paying extra for direct transfers from the airport to the resort, I advise you to do it. We took a van directly to the resort and it took about an hour. Otherwise you will have to take a shuttle bus with travelers from every other resort along the route and you will have to stop at every one to drop people off. This could take several hours. If you don't mind the extra time, then by all means, don't pay extra. Also, when you get off the plane you will be confronted by people inside the airport who will tell you that you must check in with them before you go to your shuttle - Ignore these people! All agents are located outside the airport by the shuttle buses and vans. The people inside the airport are trying to sell things like excursions and tours. Listen if you like, but you DO NOT need to check in with them. Now, on to the resort. The first impression is how friendly everyone is. From the vacation agents, to the shuttle driver, to the front desk people, to the bellboys, to the maids, to the bartenders and every other worker we encountered, everyone was so nice and accommodating. Practically everyone speaks English. As we stood in line, drinks were bought out on a tray and handed out. The front desk lines, though, need to be arranged better because there is no dedicated line for the next available desk clerk. You just stand behind a line of people in front of a clerk and see how long it takes. We waited maybe 10 minutes. No rooms were available since we arrived earlier than the 3:00 pm check-in time, but we just dropped our bags off to the bellboy and went to the buffet to have lunch. After lunch we checked back and a room was available. We gave our room number to the bellboy and went to our rooms. Our bags arrived a short time later. The rooms look like they do on the websites, but they really don't do them any justice. The room was all marble and wood with a foyer which holds the closet, the mini fridge and the safe. The safe uses a four digit code that you select and is large enough to hold a portable DVD player or a laptop. The fridge was stocked with Fanta orange soda, Sprite, Coke, diet Coke, bottled water, a gallon jug of water, beer, and mineral water. Every time we drank anything it was replaced the next day. The bathroom was all marble with a large whirlpool tub, a separate shower with an adjustable massaging shower head, a wall of shower heads that go down the length of the body, and a hand-held wand. The toilet is behind a frosted privacy door. There is also a lighted vanity/shaving mirror. As seen on pictures of the hotel there is a cut-out in the wall between the bathroom and the bedroom. Some rooms have frosted privacy shields, some don't. Ours did. We had a king bed and a 37 inch TV with a satellite receiver. There was a separate sitting area with a sofa, a matching chair, a work desk with chair, and a table. The sitting area led out to a balcony with two chairs and a table. There was also a retractable clothes line to hold wet swimwear. There is a phone in the room which have high rates to call out but is free to receive calls so you can give the number to people in the states and they can call you free of charge. During the length of our stay our room was kept very clean with clean towels whenever we wanted them. The ceiling fan and air conditioning were great and kept the room cool. The room air had lots of moisture, but there was no strong musty smell. We only noticed a slight damp smell in our clothes after we arrived back home. One washing took care of that. Navigating the resort was pretty easy when you learned how. There were 10 buildings three floors high linked by walkways. Not all buildings had elevators so you had to walk to the next building to go up or down. The pool was large with a huge elevated whirlpool and a swim-up bar, with bar stools, in the middle. I know in many reviews people talk about playing the "towel game" with pool chairs, but although some people did save chairs, we never had a problem getting one no matter what time we went to the pool. The depth of the pool went from wading length at it's lowest to 4' 7" at it's highest. Although you can go to the bar for your own drinks, there is waitstaff patrolling the pool area to take your orders and bring drinks directly to your chair. The wait was never that long. The beach was located down by the Mayan Beach buildings. Although the sand was soft, if you want to swim in the ocean you must bring water shoes because the shore has a rock shelf and the surf is full of rocks and coral. Also the water was very salty. Sensitive skin may peel. The Grand Sirenis has many bars scattered throughout the resort and drink service was pretty quick at each one. Some people tip thinking that it gets you better service and better drinks, but I didn't notice a difference between those who tipped and those who didn't. The bartenders were friendly to everyone and delivered drinks without waiting to see if they were going to be offered a tip. And if you have a problem with the strength of your drinks you can always ask for more booze. Also, unless you ask for a specific brand, you will be given low-end liquor. If you want a premium brand just ask for it. The Sirenis also has many restaurants including a main buffet for breakfast, lunch, and dinner, a poolside breakfast and lunch buffet, and many specialty restaurants that you must make reservations for. We made our reservations with our building concierge the day after we arrived for three specialty restaurants and got every one we wanted. Unfortunately we were so busy we only made it to one - the steakhouse which is located in the breakfast and lunch poolside buffet after 6:00 pm. The food was excellent. The steaks were perfectly cooked and they even accommodated my cousin's boyfriend when he wanted another steak. The wine and sides were good as well. The regular buffets ranged from OK for some foods to great for others. As with any buffet if you look long enough you will find something you like. A couple of nights were theme nights in the buffet with food reflecting the theme. A limited room service menu is available until 11:00 pm. The wait was typically 30 minutes. Entertainment was varied and took place in the large theater located next to the lobby. Check the board next to the theater to see what show will be presented that night. The disco is located down a path through the woods that is accessible by tram. The ride down was fun and a little scary which made it even more fun. Music was a mix of popular American music, dance music, and salsa. Iguanas walk the grounds like you would see squirrels anywhere else. They run if you get too close, though. There were walking trails and many free activities scattered throughout the resort and you could check the board to see what was happening, where, and at what time. Although Grand Sirenis bills itself as family friendly, and there is a kid's club down by the beach, many of the acts in the theater, and many of the contests they have throughout the resort are adult-orientated. So be aware. Also, be aware of the shows on the television. After 10:00 pm some channels on the TV become pretty hardcore. We have a show here in America called Wild On that airs on the E! entertainment channel that shows how wild people get at popular vacation spots. In Mexico it is called Naked Wild On and it shows men and women frontal nudity, and graphic sexual situations. Also they have movie channels that show uncut films with all the language, nudity, sex, and graphic violence intact. Remember, this was not Pay-Per-View. It was regular TV so be aware. As nice as Grand Sirenis was, it was not without a few problems. On a couple of occasions the electricity went out for about an hour as did the hot water. The front desk was very apologetic and assured us everything would be taken care of soon. The weather was great every day we were there with the exception of one day when we had torrential rain from about 3:00 am to about 3:00 pm the next day, but that was it. We also took a shopping trip to Playa Del Carmen for $50 round trip. Our shuttle driver asked when we wanted to be picked up for our return trip and met us at that time. Exchange rate is 13 pesos to every dollar. Some places give pesos in change while others give American. It's best to have small bills handy. The resort was only at 37 percent capacity so everyone was at the Riviera Maya side and the Mayan Beach side buildings were dark. Even so, we were treated royally and a few inconveniences aside, we thoroughly enjoyed our visit to Grand Sirenis and would recommend it to anyone.
