we own two weeks of this timeshare stuff. it's at a 5 star resort on maui. and at $700 a week, per year, with everything included. so about $25 per person a night for a family of 4. it's pretty much a steal. this is the place:

another up side is you can trade the time you own for time at another place managed by the same company(e.g. Trading Places) for usually nothing. and that can be any where in the world.
