Hi - hope someone can help... While on the Fantasy MV we made a reservation for a June 2013 med cruise (reserved with air and transfers). We tried to book a Cat 7 "secret verandah" but they were not available, so we booked a 5C, assuming that was the cheapest category with the plexiglass verandah. After we got home & I checked Disney's website, I see that for our cruise, Cat 5B is actually slightly less expensive and would move us up to deck 7 (which we would prefer). Questions: If I modify this reservation online, will the price include the 10% discount? Will we still have the platinum OBC of $350? Will it mess up the reservation at all, since it is a "cruise-air-transfers" combo booking?
