Don't get a cabin in the MSC Yacht Club. Sharing tables isn't allowed in the Yacht Club restaurants and switching to the regular dining rooms is a pain. The matre d's in the dining rooms do a back and forth he's yours to take care of not mine.
In the Yacht Club you can say Peter, Paul, Mary and i are Yacht club members met and want a table for us but you can't do the i'll share or join anyone.
