Our original plan was to arrive in FLL at 6am the day the cruise leaves at 5PM. Princess felt that since we were coming infrom Canada via Las Vegas that we may not be allowing enough time for snow delays etc. They requested that we come in the day before and that they would get us a hotel at discounted rates. ISo we changed our flight to arrive at 6AM the day before, gives us almost two full days to explore FLL and it only costs us an extra 150.oo (with exchange). Worked out great for us.
Out TA is awesome, also got us a room upgrade already as well, not category, just better room for same price as the one we booked.
