shondie, it sounds and looks like a pretty nice place. Check out www.tripadvisor.com
and type in Hyatt Regency Pier 66 Fort Lauderdale. It gets some great reviews. 4/5 on the scale. Not too shabby! I don't think you need to worry. While on the site, do the virtual tour to check out the rooms.
Trip advisor is a great resource that I always go to.
And, keep in mind, you are ALWAYS going to get complainers, no matter what.
