Hey - we'll be there at the same time! We're going to be there from the 11th to the 16th.
We booked on hotwire and the woman said it was a customer favourite. The tripadvisor.com reviews are mixed. I called and upgraded my room to a 'sleep number' bed room for 10 bucks more a night. I have a feeling that might get me a better room as it seems to me from teh reviews that some are nicer than others. If you go onto www.tripadvisor.com , you can see reviews and if you search in teh Kissimmee forum, you'll see some posts there too.
I haven't stayed there in a while but it was OK - I won it on priceline and for the money I paid it was good. Very close location to AK and Sherbeth Rd.
