Just to be clear - the "90 minute presentation" will end up taking 3-4 hours of your vacation time. For us it took 4 hours as we had to take a shuttle bus to their presentation center and then another shuttle to the grand desert resort. The resort is very nice and we actually did end up staying there using a Priceline vacation package . For that we only paid $250. We would never buy the $20,000-50,000 timeshare Cost , plus the annual maintenance fees, so they had no chance at a sale with us. There are ways to stay at their resort for far less money then buying into their timeshare
