Unfortunately we chose to take a cruise with MSC Musica leaving Buenos Aires January 4, 2013. Boarding the ship took five hours of a disastrous standing on four lines without any help from either the port authorities or MSC, who had two or three employees to take care of three thousand passengers.
Waiters, clerks and supervisors were for most of the time, either rud, ignored you or did not solve your requests, sometimes in very unpleasant ways. Forget any special help for families with children, or care for older adults. We even had a run in with an employee for her insulting attitude towards an elderly couple.
Food was below average and dinig at the diners was not worth the food, since they try you to encourage you to use the special restaurants, paid separately of course. We quit going to the diners and went to the buffet to avoid that niusance. After hour snacks were either absent or extremely basic.
