Two of the most important things to do when going on a cruise: 1. If you are flying to to your port destination,NEVER book your flight to land on the same day as the cruise, incase there's a delay--you have some buffer time. 2. When boarding you have to check your luggage upon embarkation and it will be delivered hours later into your cabin. ALWAYS have a carry-on that has your medication, and other essentials like a change of underwear, toothbrush, bathing suit, etc...
