Several years ago we got a number of spectacular weeks for FREE under the XYZ program. They were shoulder or off season weeks, but we like to travel then. Used XYZ's to go to Marriott timeshares in Park City (Summit Watch), Fort Lauderdale, Williamsburg (original section multiple times), Myrtle Beach, Orlando (Grande Vista), Singer Island (Ocean Pointe) and Phoenix. All were 2BR units except Fort Lauderdale where we could only get a 1BR. If they still had XYZs, we would likely still be using Interval for more than the occasional Getaway we purchase now. The replacement program does not offer this ability, and in fact I have been told that almost all Marriotts are excluded from this program.
