Invitation from Hell! Avoid at all costs. While I've never signed up for one, I have attended the free seminars where they really pressure you to sign-up. I've got close friends who've signed up, and always complain they can never get the property they want at the time they want, so always end up going somewhere like Fiji (4 times to stay at the same place!).

Yes, it's another timeshare, and if you've been to Hawaii, you can also see them in shopping centres and street corners in Waikiki area offering you limo rides to their "function centre" for free drinks and food...! Or free tuk-tuk rides in Phuket and Pattaya for the same sort of thing.

Buyer beware.
