We have stayed at both the Hyatt Centric and Riverside, but not the Crowne Plaza. The Hyatt and Riverside are located in the same area with lots of restaurants and activities (near the on-off boats). The Hyatt is a newer property very clean and modern but a little sterile for my tastes. The Riverside is an older hotel with small, clean but, comfortable rooms. I believe that some of the hotel has been refurbished. The only thing to be aware of is that the hotel is located a few miles past the port if you are traveling from the airport. Either way, I would definitely stay at both hotels again.
