I booked CSA through US Airways Vacations back in February for 6 nights begining July 22...Monday through Sunday. Now it looks like we can leave on Sunday and we would like to extend our vacation for one more night. I can adjust my flight but every website including Couples and US Airways say there are no rooms available OR that I must book three nights in a row in order to book a room. Has anyone every encountered this?? Any suggestions? Thanks!
