Surprisingly (considering how successful they have been), there are very few actual kidsuites in Orlando. HIFS is the prime example, but HI Sunspree and HI Maingate East both offer decent facilities (they were the originators of the idea hereabouts, and HIFS built on their ideas), while the superb Portofino Bay at Universal Orlando has a few kidsuites, and the Hard Rock Hotel (one of my all-time faves in the area) has 14 kidsuites and excellent family facilities throughout the hotel.
