We did a lifestyle preview this past February "just to look around." (wound up buying a lot in St James and will close on our house November 17!
)
We didn't receive much - free round of golf, 10% off at some restaurants, free movie passes. We could, of course, check out all the amenities (you're given ID cards to access rec centers, katiebelle's, etc.) Our sales agent also gave us tickets to a show at the Savannah Center which was great. I believe in the past the "extras" were much more. Villages just doesn't have to "entice" people anymore. One visit and most of us are hooked.
I did zumba, line dancing, enjoyed the pools. My husband golfed. We stayed in a lovely home. Had access to a golf cart and bikes. The "Recreation News" that comes out on Thursday lists the activities/clubs you'll be able to check out while on your preview. So much to choose from. I ran out of time!
Have a wonderful visit. I know you will love everything about the Villages.
