We just were at a presentation on Tuesday of this week. We got our offer through Starwood Resorts - the Sheraton Vistana Villages. We were nervous about the presentation but in the end, they CANNOT keep you more than the 90 minutes by Florida law and they give you your "gifts" (money or park tickets) when you check-in so you can use them before the presentation. We had a 2 bedroom condo, full kitchen, laundry, etc got 2 Dsiney park tickets, 2 Disney waterpark tickets, $30 in Planet Hollywood vouchers and 2 movie passes and for 4 nights, it was $449 plus tax!! Call Starwood Hotels and ask for the Touch of Magic Package on a Discover and Saty package. It's a 5 star resort - you won't be dissappointed!
As for the presentation, it's uncomfortable....you have to say no to about 3 different levels of staff. But if they see 0 interest, they let it go. They told us admittedly that most people go assuming they won't buy in. In fact, we ended up buying a 2 year option that we can get out of in 2 years - it's an amazing value if you go at least once a year, and like nice "home away from home" accommodations!
GO FOR IT!
