I just called Enterprise for myself and renting a car for a day is looking like a decent option. Since we are coming in the day before it was $60 one way dropping the car off in port canaveral the following day. This way we can do what ever we want the night before the cruise as well.
Hi, we will be making the same trip only in july. After reaching different shuttle services I found it cheaper to rent a car at orlando, turn it in at port canaveral before the cruise and then do the same on return renting at port canaveral and turning in the same day at orlando. shuttles for 4 people were 160 to 180 and i did the car rental for 98 total. thrifty full size.
