First of all, let me say this was our ninth cruise and first with Celebrity. If traveling from Ft. Lauderdale, try the La Quinta hotel. Great place, not run down as some others have complained about hotels in the pier area. Your stay includes transportation to the pier which was great.
The embarkation procedure was fantastic. No lines and everything was ready for us to walk up, get our room card and board. As we went to our rooms the room steward greeted us and asked us a list of questions about how we wanted our room set up and any special requests we had in relation to his service. All through the trip we were totally happy with his service.
The food was plentiful and tasted great. During lunch many people were unaware that there was a made to order pasta bar and sandwich bar at the rear of the ship. These same people were not aware of the waffle bar for breakfast. You cannot skip these. They are almost a dessert they were so good. If you don't want to eat dinner in the dining room you can go to alternative dining, which requires a reservation but it allows a less formal dining area with complete waitservice and only two menus. The menus are alternated each night so not a huge selection but very good. My one complaint is that if you choose not to have a "sit down" dinner, there is no dinner buffet which would allow you to just grab a quick bite then go off to the casino or hang out on the decks. It was a little annoying to me since I don't always want to spend two hours eating dinner.
Celebrity is a little different. No animal towels on your bed and none of those activity announcements every half hour to disturb your naps. They had a noon update and that was it. The entertainment was great with an a cappella men's singing group, Lighthouse, which was the the best shipboard entertainment I have ever enjoyed.
As for shore excursions, we did the 4x4 thing on Aruba which was okay, but there were four of us and we would have done better renting a jeep and touring ourselves.
In Costa Rica we did the Aerial tram which was also just okay. The sale is that you are in a rain forest, which you are. But it was cut years ago and is still 30 years or so from being back to where it should be.
In Acapulco we did our own cab thing and got to enjoy all there is to see. For souvenirs, avoid the government area flea market (overpriced) and just walk the shops around the pier. Plenty of them and never pay what they want. Bargain and the prices drop 50 to 60 percent.
Cabo San Lucas of course was beautiful and we fended for ourselves. Paid 10 dollars per person for a 1 1/2 water taxi tour of the bay which we thought was a good deal. They will even drop you at lover's beach and come back for you later. We found the guy at the end of the pier and english was not a problem for him.
All in all, great trip. Celebrity is a great cruise line and would not hesitate to travel with them again.
