I've been a member of Interval for several years, and I'm constantly on the website searching for 2 bedrooms at either Surf or Ocean Clubs. (I prefer Ocean Club) I've NEVER seen this many openings at the Surf Club! Is something going on that I don't know about? I don't own at either, just trade into.
I suspect you're correct about the "over-expansion". We bought 3 years ago and love the place, but I'm glad we bought an Oceanfront 2 BR villa. There are only a limited number of these and they can't add any more since they are at the front of the Lighthouse Tower. It cost us some extra $$$ at the time, but it has been easy to trade (Maui 2 years ago) when we need a change of scenery.
Lot's a plusses for going to the Surf Club, but there are so many rooms.
