We are staying at the day in in cocoa beach on 1-17-03 and cruising on the 18th! Do you mean the port canaveral port? From what I here it is only about $3. At least that is what our shuttle service is charging.
We are going on the Pride. Which ship will you be on?
That low fare makes sense since the Port Canaveral crusieport is located along a locally known back route out of Cocoa Beach. Go North on A1A and where the route swings around to the Northwest, there's a little street off to the right, almost straight ahead from your previous direction. That little street is Port Canveral's Atlantic Ave/Jetty Park Rd. It dead ends into the Port Canaveral dockside street. Turn left at the T intersection to get to the terminal. That backway also allows you to turn right into the terminal parking lot; buses coming from Orlando have to wait for traffic to clear to turn left.
Some friends showed me that route several years ago. I always use it when I'm in the area, because I like seeing the ships and I use the backway to get over to Cocoa Beach.
