Heide,
In addition to the activities mentioned, TV has two bowling alleys, two movie theatres, a performing arts theatre, every type of arts and crafts groups you can imagine and a community college.
First step: 6-day Lifestyle Tour, I agree. Unless it has changed, it's only $75 a night, includes a (slow) golf cart and two bicycles, free meals at a variety of restaurants in TV and (I know you don't play, but) two free rounds of golf at any of the championship courses. Why would you need a golf cart, you might ask? It's a favorite mode of transportation here for getting around in TV.
You won't believe how much fun it is here. You won't believe how friendly and welcoming people are, how easy it is to make friends, how many things there are to do.
Please come!
