This was my first cruise on Celebrity, and it blew me away. I've cruised on Royal Caribbean and Carnival before, and this was the best.
Embarkation was on October 10, 2005 in Los Angeles Birth 91 (i think) at the World Cruise Terminal. Not the smoothest thing to do in the world, but it wasn't horrible. We got there at about 11am. We went in some doors and were told to go outside, but not really what the procedure was. This was by a port employee. Once outside, we assumed we were to line up in a line that was forming. Eventually, we found someone who gave us luggage tags we filled out. Then a porter came and took our bags. The only bad thing I can say here is it would have been nice to have a Celebrity employee there we could ask and confirm what the proper procedure was. The line started moving at 11:30am, and we were on the ship by 12:30pm. Was greeted with champagne and orange juice. We were told our room would be ready at 1pm and it was. We just hung out at the buffet before then, and toured the ship a bit. Later in the day, our bags were delivered to our room, one before the lifeboat drill at 4:30pm, and the rest after.
There was lots of activity and give away's going on the first afternoon before departure. We didn't stick around for that as we mostly relaxed, toured the ship a bit, and ate.
