The basic principal of BUY where you want to vacation is a good plan and generally works.
If you are looking at Hilton level quality, you need Hilton, Marriott and Starwood. Wyndham is a cheaper cousin only because it has a nice resort or two around (and it really is much cheaper if you can forget about the nickle and dime fees in the points system).
Yes, there are FIXED weeks at many resorts in South Florida - generally,
older resorts. If you are looking at those, BUY exactly what you want as far as unit location, size and most importantly, the week number. I am a happy camper in any of my South Florida fixed weeks ... and all my family & friends try to tag along.
Denise's recommendation to RESEACH is very important. Easy to buy, difficult to dump a timeshare ownership. And believe if or not, TS resorts seem to have personalities unique to location and sometime, the season. Resorts that have a large number of fixed week owners even more so.
And robert55, thank you for those kind comments. I have been to many different TSs in South Florida on the Atlantic side ,sometimes stay or doing a day visit (only have traded into South Florida a few times). You must have a decent trader and deposit & request early to get Feb and Mar trades; I was definitely down on the idea that a $1 eBay special would be exchanging into a prime season 2/2.
I always talk to the people out at the pool, hot tub, elevators, lobbies, and front desk staff everywheres. At the resorts I own, I know as many names and faces of owners, exchangers, renters, and staff (including the housekeepers, not just resort managers). It is amazing how much you can learn as to where people are from, why they pick that resort (either 15 years ago to buy or last week to rent). It is great when several people get into the conversation, sharing tips and secrets. Just last month, I did a 4 day tour of the resorts to find out 2010 MF projections and delinquences for 2009 MFs. Yes, it was hot - but no big hits in MF increases ~2%, but one resort is planning a Special Assessment, also
