On our cruise to Alaska on the Majestic scheduled next week, we made our bid in February and at the end on March our bid was accepted. We upgraded from a basic balcony stateroom to a club class mini-suite for an additional 265 usd pp. on this 8 days cruise. We are very happy about it. We made 3 bids for deluxe balcony, mini-suite and club class mini suite and got the club class. We wish it works for you! they can accept bids until very close to the sailing date.
