We are taking our second Disney cruise in the spring. Last time we did a 4 day and left our car at a hotel and took the shuttle. This time we are doing a 7 day. We are traveling with two other families. They want to stay at a hotel, leave our car at the hotel, and take the shuttle. Is this what most people do, book at a hotel, leave their car for a week, and take the shuttle to the port? Is there any advantage to leaving our car at the port?
