does this mean really one should own a marriott and a hilton.
If I understand your question/comment correctly, you are wondering, "
Is there no such thing as ONE perfect timeshare?" and "
Might members of this community feel a need to own a smidge of multiple timeshares in order to reach all of their goals?"
If those are your questions -- then I'd say, "RIGHT!" to the first and "YES" to the second.
While I don't own Marriott, Hilton or Hyatt -- I do consider myself successful and happy with my blend of timeshare products. Of my mix, two are mini-point systems for flexibility, one EOY week gets me around the Grand Pacific Resort exchange block covering most of SoCal, two are powerful traders while one is an inexpensive trader, etc.
It seems to me that every major timeshare brand has their "hook." Some special feature to make that product unique in the market and desirable to the buyer. For Marriott, the 24-day "Marriott only" exchange window (the hold described above) is attractive if you plan to visit Marriott resorts. One buys DVC if they really value the "on site" experience. VRI resorts offer both discounted exchange fees and internal-exchange priority to their owners. If a property has very special view units -- you'll be told that these are only available to owners not exchangers. (etc, etc, etc.)
If you are flexible and easy-going you may be happy getting the occasional trade into "any property near <location>." If your requirements demand an annual stay at <ABC RESORT with OCEAN VIEW UNIT> you might want to consider owning at ABC Resort instead of hoping for the exchange. Make sense?
