This was our first cruise and aside from a few minor complaints, it was amazing.
We booked a transfer from the airport directly with Celebrity and it went very smoothly with the Celebrity representatives at the airport extremely easy to find. Embarkation took maybe 5 minutes at most and we were on the ship.
The concierge class room we were in was a great size and the balcony with chairs and foot stools was perfect. The bathroom had all the amenities you'd need and the shower was especially nice. One of the perks with concierge is the afternoon snacks and we managed to get both a fruit and cheese plate every day which were nice touches. Our stateroom attendants did an excellent job making up and turning down our room and it was always spotless.
The cabin and balcony were spacious and the foot stools you get in concierge class on your balcony are a nice touch. Hardly any noise to speak of and a very smooth ride. The bed was comfortable and the bathroom was very nice as well. Lots of storage space.
