Sorry, no personal experience, but you may want to check here if you haven't already.. There are 2 Sheraton Vistanas' in Orlando, I am assuming you are staying at the one in Lake Buena Vista.. Hope this helps..
We stayed at Sheraton Vistana Resort in December of '05. We had gotten a post card in the mail for a super great deal from Westin. Anyway, we had a lovely stay. It was very peacefull there and real pretty grounds. The resort buildings could use a little refurbishment on the outside, but the inside was perfect. The bed was comfey and my kids both said the sleeper sofa was comfey too. We had breakfast in the little restraunt they have there and it was very good. It's served buffet family style. We didn't get to try out the pools, which was a dissapointment. It was just too cold.
We stayed there in the mid-90s. The condo was very comfortable, super big and clean. It's close to the parks and even closer to the marketplace. I don't think you'll go wrong staying there...have fun.
I stayed at Vistana village it was really good. Very clean, nice pool very, very spacious rooms. They dont have a restraunt on site but they do have kitchens and theres a publix down the street. If you are planning on stayying at the Vistana Village ask them for a room away from the construction the past two years they have been expanding im not sure if they still are. Overall id rate it a 9/10 great resort !
We usually stay there and it's wonderful! Lots of room; like an apartment, but it's more vacationey, somehow. I love the smell. There are several pools, weekly activities, and good restaurants that are not crowded where the food is reasonably priced. It's also really close to Walt Disney World and Kissimmee, and Publix, a gas station, lots of restaurants, and the outlet malls! It also happens to be next to Vista Way.
