I am a Worldmark owner with 28,000 credits available, I have access to both RCI and Interval. I am trying to get 2 two bedrooms for my family at one of the "nicer" resorts (Marriott, Hyatt, Hilton, Westin, ect.) for this summer. I have been searching since September and haven't found much. First time trying to exchange and also a new timeshare owner. Am I wasting my time or is it possible to find something?
