Where do you own and what size unit/dates are you looking for? Depending on what you have, you might be able to find someone that owns there that is willing to do a direct exchange without going through II/RCI/etc. If you use II or RCI, there is a resort fee of $420 for a 2BR unit and Vidanta has a bad habit of restricting access to some of the amenities (e.g., the Beach Club, Grand Luxxe pool & custom burger restaurant) for exchangers as an incentive to get them to attend a sales presentation.
The hotel room/studio has a much lower resort fee, of course. Also, you can get a better resort fee through SFX if your TS trades there. It all really depends on what you're looking for.
