I'm thinking of using a rental car from US to the ship. I haven't booked land portion yet. I thought we'd do 2 days at US before cruise ( we are huge Harry Potter fans) and several days at WDW after the cruise. We are a family of 5. Are there rental car agencies right near the port?? Which ones?? Does it make sense to drop off car, go on cruise and then have another car rented when we get back from our 4 nt cruise. It seems like it might be cheaper to rent a car than take Disney transportation for 5. Any ideas??? Thanks so much.
