I can offer my opinion on the 3 resorts. My husband, children, 7,6and 4 and I just got back from one of the best vacations. We went through RCI to the Wyndham for a week and spent one night at the Comfort Suites to access the Atlantis.
This website was very helpful for tips for budgeting money and time.
We requested the C tower with ocean views on arrival at the Wyndham. We were told it was not available for RCI guests. It was worth making an little bit of a stink to get this, and did, because waking up to the sunrise over the ocean is spectacular. We took advantage of the kids club twice for a couple of hours to finish some business and during rain and the staff the staff there was great. The kids really enjoyed it and asked to go back. We booked a boat right at the beach front to go snorkling--cost about $35 per person and $10 for the kids. We had access to cayaks, paddle boats, water bikes and snorkling gear all included at the beach in front of the Radisson. The slide at the Wyndham was another great attraction for the kids even though they explored all the pools on the Wyndham and Radisson grounds.
While staying here, I walked to the City Market and Burger King a couple of times and took the bus back instead of going to the gym.
The fitness center at the Wyndham is nice and does have cold water at which you can fill your bottles to bring to the pool.
One morning we did not have cold water and showered with the kids at the fitness center. The Wyndham gave us a $50 credit.
While there we ate at Johnny Canoes one night. The prices are about the same as Bennigans at home. I suggest Friday night because they have a fun Junkanoo band.
The Comfort Suites was just fine. We arrived early in the morning, checked in and were able to enjoy 2 full days of Atlantis fo the one nights stay. We also were invited to enjoy their complementary breakfast on both days which saved lots of time and $.
I have the least to say about Atlantis. I had to rip my kid out of there.
We ate at The Green Parrot which had the best views and, Marina Village Pizza. Get a pie for $30. When at the pool there are concession stands that offer a family pack of 4 burgers, 2 fries and 4 sodas for $22. The burgers really were large and this was plenty of food.
I brought some snacks from home to eat poolside.
My tip: In addition to sunscreen, swim shirts were helpful. I bought some at Target for $12.
.I will post again with my husbands take on the things that he did and I am happy to answer questions.
