Last call from the RCI website
Last Call vacations are clearance-priced vacations that are typically available less than 6 weeks before check-in. The accommodations are at the same great RCI® affiliated resorts, with the same great amenities, as other RCI Exchange or Extra VacationsSM Getaways.
NOTE: Last CallSM vacations are paid for with cash. You do not have to exchange your deposited week to book a Last CallSM vacation.*
