Wow, that is a good price!
I never went through the timeshare pitch, but I understand its one of the more low keyed.
We were in the Lakes section. The Lakes and the Cascades are the newest sections of the resort. We liked the Lakes section because my youngest likes a zero entry pool, and it had the only one on Vistana property. The villa itself was very pretty, with a balcony overlooking the lake. Very quiet and serene. The Cascade section is the newest, and closer to the front of the resort and the main activity area. Its also the most coveted area to stay, so don't bank on getting a villa there. What we did was signed up for Vistana's Diamond Lane (on Vistana website) and made our request there to stay in Cascades or Lakes, then called a couple of days before to confirm. When we arrived, we were able to use the Diamond Lane check-in and avoid the long lines to check in, and were assigned a Lakes section room.
Vistana is very close to WDW, about 10/15 minutes door to parking lot to MK, Epcot and MGM, a little further from AK. We really like the resorts on 535 as opposed to 192, and never encountered any traffic, even when we stayed there in high season.
