The time you get on the ship depends on the debarkation of the previous cruise. It can vary by more than a hour. Usually any time from about 11 to Noon, but I got to the port once at 10:50 am and everyone that had arrived was onboard.
We just got off Ecstasy the 14th and got on the ship by 11:00 with regular boarding. Very fast since we got to terminal about 10:15. When we got back we were off the ship by 7:30 with self-assist. Fastest ever. We always stay on the empress deck as it always is one of the first decks to go. The ship seems to have remodeled since we were on it last time right after they added the balconies. New colors and seating. Antime dining was a little more confusing since on most ships there is a seperate line to go into dining room but on this cruise everyone had to get in one line. Otherwise we had a blast. Have a great cruise. P.S. The water slide is a blast even for a "67 year old kid"
