I LOVE Vistana! I own two 2BR weeks there in the Lakes and Cascades sections...the newest at the resort. However, like MissDisney said, all older areas are in the process of being refurbished, and many areas are already done! The entire resort is going to be GORGEOUS when it's done!
There are plenty of onsite restaurants, a general store, an ice cream parlor, miniature golf, activity and arcade centers and a DAILY activities schedule that is so awesome, you won't even have to leave property to have the vacation of a lifetime!
We went in 2007 for 18 days...the first week was at Vistana and we VOWED not to enter ANY parks that week and just enjoy all the resort has to offer. We had THE BEST TIME!!!!!!!!
You will LOVE it...let me know if you have any questions.
