Hasn't been a problem for me. I often have access to a two bedroom resort if I need it, and can often book several rooms at a time to take along my friends or inlaws. It depends on how far we want to go. There's no black out dates and the friendliest customer service. The best part are their prices. Their "hot weeks" run as low as $299 a week for all of us, and never more than $799 a week, even if we have our family re-unions in Hawaii at a beachfront resort.
