You might want to participate in some of the clubs and activities. I suggest that in advance of going that you go to
http://www.thevillages.com/Recreatio...Activities.asp then select the link for Recreation News & Activities on the left side. This will open a pdf of the current rec news that lists many of the activities and their locations. You definitely want to spend at least one evening at Katie Bells in Spanish Springs, especially if you like dancing. A visit to the town squares is also a "must", particularly for the dancing and line dancing.
Taking the free trolley tour is a great way to get a big picture view of the community. Every morning you will receive a newspaper where you can also find a list of open houses for the day. Of course, you can also arrange a day for your realtor to show you around.
Whatever you do, be sure to plan some time to just sit and relax and "smell the roses". Have fun and welcome to The Villages!
