I need to change our stay by 1 day to a 4 night stay instead of 5 nights. I booked it that way originally, but extended it until I saw which flight days would be the best price. It is under the summer free quick service dining promo. I tried to just change it online, but it wouldn't let me. I guess the promo is no longer going on? I think I need to call tomorrow. Does anyone know if this will be a problem?
