I agree that the lifestyle preview is the way to go. Definitely go on the trolley ride (you get a better "lay of the land"). Even if you rent a car to get here, rent a golf cart for a day or two and just ride around. Invest the $5 in a Villages Map (they can be purchased at the Mercantile stores in either town square) and ride around. Even though I bought a house on my lifestyle preview (found a great one I couldn't pass up) I make a point to take a ride and "get lost" each time I come down to stay for a while. It is a great way to see where roads lead, what the characteristics of the various neighborhoods are and if you rent a golf cart, you are paying for the gas so might as well use as much of the tank up as you can
