We will be going to Epcot on our last day and will be starting the drive home at the end of the day. We drive a midsize SUV and use a luggage carrier that attaches to the trailer hitch. (Our suitcases will all be inside of a large zipped bag that's tied down to the carrier, but there's no way to lock it. We will put computers and other valuables inside of the locked car.)
Will our luggage be safe in the carrier while we're at Epcot?
Is there valet parking available that might be safer?
