We live in LA and would like to fit the space center in with our WDW & cruise trip without spending another night at a hotel. There are 7 of us and I presume at least 12 pieces of luggage. We will arrive at WDW on Tuesday eve, spend Wed-Sat at WDW then go to the cruise. How can we fit the space center in with about 12 pieces of luggage? Is it possible to rent a car at the port after the cruise? We would probably have to rent two cars but then our luggage would be stowed in the cars while we were at the space center and then go on to the airport later in the day. Any other ideas? Thanks in advance!
