Spaulino,
I see that you are from Ca. I am from the San diego area. I think that my location is good for taking advantage of Getaways where we can do a "drive-to" vacation.
San Diego (lot of Welk availability)
Tahoe - lots of availability, especially somewhat off season
Palm Springs and PD - generally good availability except in the spring
Newport Coast - Kind of rare for a GTW. But occasionally I see something
Capistrano - fairly good availability although I'm not sure how good the gtws are financially
Lake Havasu - good avail
Sedona - generally good avail esp. during off season
Phoenix - ditto except not much inventory in the spring
San Francisco/Napa - not a lot of inventory but it does show up occasionally. If you're watching, you may be able to grab it.
If you can travel on the shoulder seasons, consider getting your membership about 5 months in advance. That's when new stuff generally shows up - - sometimes earlier or later. If you wait until say, a month or two b4 travel, the nicer places and units may have already been placed.
