I just stayed at the new Radisson in December - LOVED it. The room furnishings are absolutely amazing and the service was fantastic.
I think a big difference btween the Radisson & Hyatt is the Radisson has a HUGE beach and their pool area is broken into two parts with two pools (probably the length of a football field), so you don't feel "packed in" at the pool. My husband & I walked over to the Hyatt and people were like sardines there - it was booked that weekend, so I couldn't get in, but I'm more than happy that we were at the Radisson.
