We stayed for one week in March and my husband and i both liked the property. Sure it is like most people say not a fancy resort but it is nice and the service was great and very friendly.
We had a beautiful bay view room and i am sure that made a difference. Would recommend to book a bay view room. The restaurant was good, also i have to say that with all the other options we ate only twice there. It was so much fun to try different places every night. Our favorite was "snappers" and "marker 88" both had great food, atmosphere and service. The only place we really did not like was the "bayside grill" did not care for the food and atmosphere. The service was okay.
The Tiki Bar at the marriott was fun and they had live entertainment on some nights. We were not impressed with the diving. We are both certified diver and so far we dove at serveral destinations in the caribbean and it did not compare to that.
One day we drove to key west and as much fun as it was, we both were happy to go back to key largo and the more relaxed kind of style there.

The room was very clean and nice with a view of the bay and the sunset was beautiful. The beds were very high, and there was a shower only in our room. The pool was clean and heated and there was a bar poolside. We had a great lunch at Gus'. You can go snorkeling or diving through "It's A Dive" located on the grounds. It was very convenient and wetsuits and prescription masks and other gear was included in the price. The crew were very nice and helpful. They also had waverunners to rent. There was a beach, although it was small, and you could relax on the hammocks that are scattered across the grounds. I would highly recommend The Fish House, Key Largo Conch House, Hobo's and Marley's for meals. We had no problems at the Marriott and I would stay at the hotel again.

The good:

Rooms were very clean! Service seemed very good.
When I arrived I was expecting mediocre at best but I was suprised that the grounds were very nice.

This was a short two night stay. My wife and two daughters age 3 and 7.

Pool was nice as well as the make shift beach. The keys are not noted for their beaches. I say this with confidence I live roughly 1 hour north of the hotel.
We have some of the nicest beaches around just not in the keys.

The bad:
No belhop-I brought all our luggage up to our room.Not terrible
but thought you should know.

my wife and I heard everything at night, very noisy.
The walls are thin- you will also hear a ton in the halls.

Otherwise a nice centrally located place to stay.
Yes, there are better places but for the price this was a good bargain. Check priceline before you book with them. There are deals to be had!
Good place to eat-Great all you can eat stonecrabs- BALLYHOOS-roughly 6 miles west on route 1 from hotel.
Steer clear of Hobos- Not good bar food.

Spent four nights at this hotel this week (March 3-6) and had a great time. I find that most people who post on this site in general are ultra critical. The hotel is very nice and everyone was very friendly (staff and guests). If you are looking to lay by the pool, have a drink, maybe do some snorkling, diving or fishing this is a great place to be. The hotel is not 5 star by any means but it is nice and fits in with the vibe of the Keys. I just feel that some people who go to the Keys are expecting something different like sprawling beaches and they are disappointed when that's not what they get. As far as the last post who said there is nothing to do I'm not sure what they were looking for. So, if your not ultra critical give it a try. The rooms and pool are nice and there are great sunsets.
