Equinox is a lovely ship, and we were not disappointed. We are a family of three, with an 11-year old who is just entering that dreaded teenage realm. Although we thought she might get bored, we needn't have worried: she had a ball! As did we.
We booked this trip back in January and had a good experience booking directly with Celebrity.
The package we booked included air travel, but not through Choice Air. As it turns out we were part of a group booking for all the other clients on this cruise who were also travelling on the same flight. This makes online check-in an impossibility, normally, but I managed to get through to a helpful gent at the airline who gave me the record locator for the outbound flight, and cautioned me about the number of other passengers on the record. We fly a lot and often check-in online, so I knew what to look out for, but I'd be very worried about the novice traveller who managed to get into the record.
Our stateroom was aft on deck 11, and, although we were at the very back of the ship, we enjoyed the walk (and the quiet) down the hallway. We were in an S1, which was very well appointed and comfortable. For two adults and a child, it is nice to have cabin space that allowed us room to actually move around without knocking elbows. The cabin had masses of storage space, with plenty of room for storing luggage underneath the bed. The balcony was terrific as it was almost a wrap-around, and afforded amazing views both to the side and behind the ship.
Some noise from above due to balcony furniture being moved, but mainly a quiet cabin and excellent location.
