My fiance and I stayed at Oasis Tulum 2-10 feb 2013 and we loved it!!!
The food was fabulous and we loved the buffet so much, we ended up eating most of our meals there. There was always free outside tables and eating by the beach with the wonderful tropical breeze was a dream.
The room was very comfortable with AC working very well and great water pressure / temperature. NO bugs whatsoever!
The place is spotless!!! Public areas and washrooms are constantly being cleaned.
The beach is amazing. But you need beach shoes to go in the water as there is a mix of sand and rocks but if you love to snorkel like we do, the reefs are just a few meters away and they are just beautiful!!! I recommend bringing your owns mask, snorkel and fins as there is no water sports club at this property. The PR lends a few masks and snorkel for 2 hours at a time though, if you do not have your own. If you like walking the beach, you will be happy..as you can easily do a 2 hour walk if you stop once in a while for a cooling swim.
There is a great choice of background music, very Zen and relaxing. No ugly Boum boum as I have seen in many other properties.
On the downside...there are not enough beach chairs so some days, you'll be stuck on your towels...but there are lots of trees for shade.
But apart from that, everything was great and we would go back there without hesitation!!!

Very far from the airport 1 3/4 h.. but very nice beach the most important thing reserve ocean front room 4144 or neer.i paid 150.00 usd. for one week in extra,it was value ,meal is good,buffet is 4/5,pizza resto is 2/5 they are in reorganisation in the staff but overall it was very good. i will return for the quality of the beach wow....you must wake up early to pick a palapa they are no long chair for everybody....1/5 you must paid for a security safe 35.00 USD 1/5

Had read a lot of bad reviews about this resort and was very apprehensive about our vacation. We had reservations at Oasis Tulum but we were checked into the Grand Oasis part of the property. We found the resort to be clean and grounds kept extremely well. The beach & water
was some of the best I have seem in cancun/cozumel area, we enjoyed swimming & snorkeling
in the protected water. Food was fair in specialty restaurants and below par in the buffets, breakfast was the best meal of the day. Stay away from Mexican restaurant in the Oasis Tulum
side of the resort, it was by far the worst excuse for a specialty restaurant we have ever experienced. Overall all for the price we paid we would return for the beach & water, if you are
looking for perfection do not go to this resort. If you can tolerate some short comings for the
price you are paying I would recommend this resort. Most of bad reviews related to the older part
of resort and we walked through it and it appeared in good repair and grounds well kept.

Read many varied reviews, stayed Jan 30-Feb 6. We traveled as two couples staying on old side of resort in garden suites (cheapest tier), here's my synopsis and keep reading if you like detail. One minor "warning"... there are two resorts here. Oasis Tulum and GRAND Oasis Tulum. Grand features newer rooms, a fancy lobby, coffee bar and infinity pools. Don't expect the sweet pools and rooftop patio unless you book GRAND.

It's a nice resort that offers a beautiful beach and pools, amazing snorkeling, entertainment and many great adventures very close. Most of the staff are very helpful, but service can seem slow at times. I think the resort is growing and they're slow to catch up. It's a "quiet" resort (only 300 rooms) for those who don't want to stay in a mega hotel and the private beach is right on the resort.

If you're looking to relax, lounge and maybe do a few adventures and don't mind a few minor issues I recommend you stay here. Regarding the complaints... Be honest with yourself, if you're high maintenance you're gonna have complaints. Yes, it smells swampy sometimes, it's the tropics. Yes, the old rooms have a few issues, a tap might not work 100%. Yes, the staff sometimes speak broken English, it's Mexico and your Spanish is no better. If you want a princess perfect vacation stay in a huge resort in Cancun with two more stars. Yes, I jealously guarded my beach towel, and beach chairs as there were few (they got more while I was staying there). If you can look past the minor issues it's a great place with abundant natural beauty, good staff and great food/drinks.

THE GOOD
- Snorkeling right on the resort. Within minutes I saw more fish and squid than I expected. Want more? Head to Akumal beach and swim with the turtles. Yes we saw some.
- Buffet food was very good, minor waits at peak times. A la carte restaurants were both great and snack bars were good as well.
- Pool and beach are amazing.
- Entertainment staff, bartenders and servers are really friendly, Emilio, Freddy, Ben, Hector, Manuel and Efrain... they were like family. Concierge service was great (Rosa and others), car rental guy was awesome. He gave us a map and helped plan a day out.
- Rooms were cleaned and stocked every day.
- Shows were varied and the ones we saw were really great: fire-dancing, circus... wow.
- We had vegetarian and gluten-free friends and they had little trouble eating.

THE BAD
- We had garden suite on old resort side and man was it noisy. Could hear the neighbors talking and blowdrying easily through the adjoining doors. We were on a similar schedule so not so annoying but wow... soundproof those doors.
- Two sides of the same resort. Grand Oasis and plain Oasis. We didn't know and weren't allowed into the fancy pools unless we paid $25 a day extra. We once snuck in at night but got busted. They were nice about it...
- Front desk staff seemed a little uninformed and maybe cranky. I guess they get all the complaints and no tips, so maybe it's justified. Just saying.
- Resort could seem a little crowded at times, making service a little slow.
- Had to pay $5USD per night for safe lock, not included in room is weird. Wifi was $20USD per day.
- Beach seating was scarce, but they got more chairs in while we stayed.

ADVENTURES
- We took collectivo (cheap bus) to Playa del Carmen. It was fast and easy, cabs could cost 10x the bus. There's a 5km shopping/eating strip, if you like that sort of thing it's pretty cool.
- Rented a car and went to Coba and Tulum ruins as well as Grand cenote in one day. All in it cost us about $70USD per person for all of that and was easy to navigate thanks to car rental guy at hotel. Way cheaper than a tour and more satisfying.
- Went to Xtreme Adventure park on Sunwing tour. It was amazing, underwater cave swimming, ziplining and more...

Hope this helps, happy vacationing.
