SookeyJo - If TV doesn't give you one as part of your visit, buy "The $5 Map" of TV. You can get them at a variety of places - the sales offices at LSL and SS are usually convenient. Or if your sales person is on the ball, they might just have one for you!
Even if you feel like there's no way in the world you'd ever buy a place in TV so quickly, bring the checkbook along.........just in case!
Many many many (did I already say 'many'?) people have done exactly that - one visit, fall in love.......and whip out the checkbook!!
You'll find tons of feedback in various existing threads containing questions and feedback from people regarding their Lifestyle Preview visit. You can use the "Search" function on the tool bar towards the top of the screen: try searching on 'lifestyle' and read through some of the resulting threads. (The Lifestyle Preview visit goes by a bunch of different acronyms: LPV, LPP, LSV, and so on. Those search terms won't generate a search - they don't contain enough characters.)
Hope that helps!
