As an owner, I've never exchanged in, but here's my question & suggestion:
(A) Is your 'adjoining week' two units the same week (concurrent), or (B) two consecutive weeks?
With RCI, you should be ok with just the one week, consecutive or concurrent, (but looks like you'd need a GC for a 2nd unit, concurrent week). I'm not familiar with how the TP/Vida relationship works. I'd suggest you call TP to get their side.
Here's what RCI says for exchanges:
You can only confirm into Mayan Palace once in a 3 year period. Maximum 4 multiple or 2 consecutive units per year total allowed at All Mayan Properties. Multiple units requires mandatory Guest Certificate; for consecutive weeks unless the owner/co-owner is not traveling. Multiple/Consecutive reservations must be confirmed at the same Resort.
Violations to any rule will be cancelled.
As far as calling Vida directly, there's always the customer support email they post here on TUG now & then. Edited to add
their email. Of course, always check out the latest on the MX forum.
