Hi, years ago, one could change cabin category later (IN to OV, OV to Balcony, etc.) and keep the "old" rate that the new category was at the time of the original booking? Sort of an "inflation protection." Is this still done on DCL? And, does it matter if I book with at TA? We are thinking of booking OV, but might want to swap to balcony later if budget allows. Thanks, Elaine
