First timer on MSC Musica and first time cruiser. Any help is appreciated. Travelling with adult daughter. This is our adventure and her pre-College graduation gift. Greek Isles, May 17. Booked with a group from Louisiana and my daughter from Florida. My questions, credit cards, packing..we already have pre-paid for 4 excursions through our travel agent. I want this to be so wonderful for her and for me too. We are not drinking alcohol on this trip and my daughter cannot....we are excited, but nervous. Please, any feedback is much appreciated.
