We arrived for an overnight stay in the midst of a dreary rainy two days. I had requested an ocean view and was pleased to learn that we were placed on the top floor in a room with a balcony. So, we ordered room service, made coffee, and when the rains stopped, sat outside during the late afternoon and evening. The room service was prompt and efficient, the room was fine, and the view was magnificent. One by one the cruise ships streamed by (the beach is next to the channel) and went east to the horizon. At one point, we watched a stream of 6 cruise ships, each lit up making a convoy to east. The maid service was discreet and attentive. The next morning, we went to the breakfast room at 6:45 am and had a lovely breakfast, sitting by the window, watching more rain - but the coffee was good, the food prepared beautifully, and (for those of you who aren't enthralled with crowds of kids) very, very quiet. I add the note about the kids because this resort has plenty - and there are plenty of parents who were not enjoying the family vacation and did not hesitate to yell at their children publicly. Be prepared. I would definitely return to this hotel when staying in Fort Lauderdale; also, please note that the hotel is a Hertz depot so it is possible to rent a car from the hotel for an excursion. Book the top floor with an ocean view - yes, it is more expensive, but the balcony, high above the kids and parents is worth it.

Stay here and be happy; you're as close to perfection as it gets.
We took a Christmas cruise on the Costa Mediterranea and stayed here one day prior and booked the nearby Hyatt Pier 66 on the return. The Hyatt was fair and located near the water taxi to Las Olas shops but was in no way the hotel the Harbor Beach Mariott is.
In fact we rebooked the Mariott for two more nights so we could enjoy it's beach. We sailed the Hobie twice; we rented the Segway scooters and got great treatment from Chris.
The food at the Riva is superior.
The pool and setting are perfect.
If you're not happy here, you're a crank and don't know how to relax and enjoy this clean and wonderful place.
We are international travelers and have found few places stateside to match this except the Highlands Inn and Tickle Pink Inn in Carmel Highlands...totally different, but wonderful places in the world. Also L'Auberge in Sedona.
Stay here and rent the nearby Club Nautica boats, and go cruising up the wonderful canals of Fort Lauderdale. Enjoy!

We have just returned from a weeks holiday here and it was brilliant. The hotel was very nice. Our room was spotlessly clean and well furnished. All the staff were friendly and helpful and nothing was too much trouble. There are two restaurants which serve excellent dinners. The piano bar is relaxed and friendly. The breakfast buffet was so good, we had a huge choice and liked the omlettes cooked to order as you watch. The pool area was great and had lots of loungers available
(we were there the same time as the person who said it was crowded and we thought that there was plenty of room and not too busy at all) There is a cafe bar by the pool that serve the best pina coladas! We also had a day in the spa which was fantastic too. I highly recommend the facials and massages. There is a good choice of treatments to pamper yourself with. There are numerous facilities at the hotel. Its got everything you could need. We did find that there isn't much in walking distance (apart from oasis cafe where we got food poisoning!) but a very short taxi ride to Las Olas Boulevard has lovely selection of restaurants and shops. We recommend the Big City Tavern for food.
We searched on tripadvisor for a hotel to stay at and we're so glad we picked the Marriott!

Attended an annual convention, great meeting place, fantastic food, and rooms were comfortable. It's a great place, once you get checked in. We spent 4-5 hours waiting for our adjoining rooms to be readied, plus some of the desk staff weren't very customer friendly. Overall I have to say they handle large groups with grace and style. Amazingly good food considering the number of people being served, very high quality and served timely, hot, and delicious. Grounds, walkways, pools all in great shape. We will go back, the convention's here next year too!
