• If you're thinking about timeshare ownership, I've found Marriott Vacation Clubs to offer the most flexibility. 

If you want to  trade houses to keep down expenses, try: HomeExchange.com or ExclusiveExchanges.com, but we aware of fine print.  There may be big fees.

If you want to rent a house of condo, check out these listings, all of which are owned by friends of mine, so I can vouch that they are good and well maintained.
