My sister and I are staying in Orlando for a week. We're staying in an Airbnb place with a parking spot that's 10 minutes from the airport and 20-30 minutes from the attractions. I would love to rent a car but being under 25, the underage charge amounts to around $400 total from car rental companies. We plan to go to the Magic Kingdom, the malls, and popular restaurants. I just have no idea which option would cost me less.
