Just went to presentation and was told you can only come to the Grand Luxxe via exchange once every 5 yrs. Does anyone know if you can book 1 week with II, and another with RCI, and another with SFX and bypass the 1 in 5 rule? Is this really strictly enforced, the salesperson told me he has seen people with bookings who get turned away at check in! I am curious as I booked 2 weeks in Nov through II and was not told of this rule, and don't want any problems at checkin!! Was the salesperson lying as they often do....
