I think a lot of people are in a hurry because they want to be settled and truly start their vacations!
They may have been up since 5 a.m., driving or flying to the port. They may have made a long trip via bus from another city in Florida.
Maybe they're wearing clothes for a colder climate, and they want to change into something comfortable.
I don't feel like my vacation starts until I am aboard the ship.
I have a 1.5-hour drive to the port, then off-load the luggage, stand in line for however long it takes to check in, lug my carry-ons with me ... I am anxious to get on board, get a seat in the Lido and relax with a boat drink!
