Winter soaring "escape plan" locations?

That's what we're thinking -- somewhere a few hours away by air carrier, so we don't spend half the time just getting there -- this rules out the Left Coast. Good to hear about Lake Louisa, I'll look into that. Maybe the topic should actually be: What else is there to do in the Clearmont area, besides visit Disney?
I personally don't need to look any farther than Seminole Lake, but thought the question worth exploring. We like Houston, so flying there occurred as a possibility....
