The best way to go, IMHO, is to rent for awhile until you find a resort that you really love AND has affordable annual maintenance fees. Try to determine how well it is managed, and if there is likely to be any Special Assessments in the near future.
Many people purchased their timeshares 15-20 years ago and are no longer able or interested in traveling. Since it's very difficult to sell a timeshare in this economy (or even give one away for free) most of these weeks are rented at or below the maintenance fees. Look at the ads here in the TUG MarketPlace, and
www.redweek.com and
www.myresortnetwork.com. The asking price is often times negotiable.
What we did is to gradually acquire multiple weeks at a resort after we had enjoyed some great rental vacations there. Two of the weeks are fixed/deeded, purchased resale through a broker. The other three were already converted to RCI Points when we acquired them via Ebay auctions. When we wish to vacation for 5 weeks back-to-back in our units, (or rent them) we need to notify RCI at least 9 months before the check-in date that we will be using our units instead of receiving the RCI Points that year. Otherwise RCI automatically places the Points in our account and we cannot use the weeks we own that year.
If at some time we decide we want to use the 5 weeks every year w/o having to remember and meet RCI deadlines, we can withdraw the weeks from the RCI Points program, at no cost, and own them from that point on as fixed/deeded weeks.
Also, since our resort is managed by VRI (a large company that manages many different timeshare properties), and we already have weeks from that resort in the RCI Points program, we have the ability to convert our two fixed-deeded weeks into RCI Points for a one time fee of $500.. If all five weeks were receiving points in a given year, we would have 330,000 Points--enough to exchage into a few high end resorts. or several average ones, and/or many weekends.
It probably sounds complicated, but it is easy enough to learn the ropes when you are at the RCI website, seeing the many different possibilities.
My advice to you is to take your time exploring many possibilities via rentals before purchasing. Keep in mind that the large exchange companies, particularly RCI, keep changing the rules of the Points program--and never to the advantage of timeshare owners. I personally will not buy into a Points program that I cannot get out of easily in the future, if it no longer meets my needs. I made sure to purchase a specific week that I can change back to a fixed deeded week, so as to have nothing further to do with RCI, if I so choose.
