MSC is refusing to allow a single to book a cabin on their ships.You can go on and book a cruise and there are lots of cabins available, but then backup and change the passenger to one and it says no cabins available!!! It will not let you boo a cabin even if you pay double the rate!!!! Have heard they want more people on board to buy drinks and spend money, We usually book 7-9 cabins and one s a single with the others with 2-3 in a cabin and many are 1 or 2 cruises from black status.. If they will not allow singles, they will lose all our bookings for the other cabins. Shame on you MSC Looks like discrimination!
