The typical MSC offer that most guests are used to requires a $500 deposit for a fully comped cabin (the deposit is different for Yacht Club), which they receive back as casino credit once the cruise begins. The reason MSC requires this deposit is that they pay the port fees and taxes in addition to the cruise fare for the guest and the deposit is their way to ensure the guest is committed to sailing with MSC. This way the guest is truly getting a fully comped experience. On occasion, MSC will receive special offers from their revenue department which the casino department does not have to pay for. Under those circumstances, the taxes and fees still have to be paid and the casino department cannot pay them under those parameters, so the guest will have to pay them. These types of offers are not as common and only happen on select sailings and are typically very short notice.
