We parked there last month also. $70 for a 7-day cruise. We had even booked the night before at the Hampton Inn on Cocoa Beach that included a parking spot at the hotel and shuttle transfers back/forth to the port, but after we checked in, we were somewhat unhappy with the Hampton and elected to park at the port anyway and incur the extra money. Plus, the shuttle that would pick us up on Saturday morning to go to the port was coming at 12:15PM!
Heck, we were BOARDING the ship at that time! No way, was I going to have to wait at the hotel for a shuttle to pick us up.
