I think I stayed at The Fountains last time we went...it's really convenient for Publix and Premium Outlets and located almost directly inbetween Disney and it's rivals....it took us about equal time to get to both.
There's easy access to everything at the top end of I-Drive and you can get the trolley up and down for a cheap price. We stayed in one of the original buildings but there was a lot of building work going on while we were there...two new blocks opposite us.
I really enjoyed it, there was 5 of us staying in a two bedromm apartment and there was plenty of space. We had great views of the sunset from the 4th floor, and the kitchen electricals and home entertainment system looked fairly new.
The master bedroom was AMAZING...it had it's own marble hot tub as well as a bathroom but the second bedroom was great too. I slept on the sofa bed and this was fine, although it did mean that I was up whenever anyone came in to make coffee in a morning, but I didn't mind because it was a trip for my 18th birthday so I wanted to see as much as possible!!!
The pool is really nice too, and you can swim from the inside to the outside and sometimes they show pool movies....mainly for the kids but anyone can go. the reception area is lovely, and the staff are friendly and helpful. We didn't spend much time in the lobby area but from what I can remember there was a shop there and a bar/cafe.
We were there during Hurrican Jeanne and we felt very safe and the staff were brilliant in providing us with flashlights and glowsticks when we lost power.
I hope this helps, and I hope I've described the right place!
