I would like to make a reservation for a 2011 vacation using some points I've banked from 2009. Possible? My use year is February. I've banked some 2009 points so I understand they would expire in February of 2011 if not used, yes? May I make a reservation now for a cruise in August of 2011 using those points? Is it the case that they have to be available at the time of travel or at the time of making the reservation?
