We left the Country Inns & Suites (the closest hotel to Port Canaveral) around 11:00, parked the car (we got ourselves a little turned around -- a car was blocking part of the sign, and we thought the word Canaveral said Carnival -- and we went looking for another parking lot for Royal Caribbean people), handed off our luggage, went through security, checked in and received our SeaPasses . . . and we were in line to board the ship sometime 11:30-11:45 . . . we were among the first to board Mariner, and I'm sure it was something like 11:45-12:00.
