> I went to a vacation club presentation for a bunch of free stuff once, it wasn't worth it.

My wife and I signed up for a snorkel tour a few years ago, one of those "attend this 45 minute presentation and get your tour for half price!" deals.

We skipped the presentation and ended up being charged the full tour cost plus something extra, I think $25/person on a $200/person tour.

That has to be close to the best 50 bucks I ever spent.
