Traveling with 12 month old

Hey there mommies I was just wondering what I would need to travel with a 12 month old. In June we will be going on a week long cruse my baby would be turning 1 a week before we leave so we're hoping he'll be walking by then (hes super close). I am a first time mom and have no idea what am doing. Any suggestions on what we would need to take with us or any tips on how to make traveling easier. We will be going by plane to FL then on a boat to a few places for a week. Heres a pic our baby boy just because lol.
