Our last trip was on Mariner and we had a great time as well - until we got back. It was the first time, they didn't park the boat at the same terminal in Port Canaveral and we never knew that you couldn't just walk from terminal to terminal. We parked at the port, but were really confused when getting off the boat because it all looked really different. Then we had to figure out where we were, wait in a huge line to get on a bus which didn't stay a line as soon as the bus pulled up. It probably took us 1.5 hours from the time we got off the boat to get back to the terminal where our car was when every other time, it was 5 minutes and we were on the road. I wonder how often that happens?
Anyway, we still had a great cruise and Mariner is a nice ship. This was back when there was a huge gash in the back of the ship because another ship had crashed into her while she was docked.
