Embarkation in Bayonne, NJ was relatively smooth. Some vehicle congestion at the luggage drop off area but not too bad. Parking lot is in close proximity to the ship and the in processing building. Plenty of help to navigate through the check in process. The lines were reasonable and this was 3 hours prior to departure.
The Summit is in better shape than most of the reviews I read. Our Concierge Class Cabin was more spacious than we had on Norweigan and Disney, incuding the veranda.
The indoor spa pool area is an excellent alternative to the outside pools and deck areas, which were crowded because the weather during the at sea days was great. No children under 16 are allowed in the indoor pool and for the most part Celebrity enforced this.
