We were very happy with our first Celebrity cruise on Summit. We would definitely cruise on Celebrity again and loved Summit.
Embarkation: We waited a very long time (2 hours-some people had been waiting even longer) for our transfer to the pier. There was very little direction or information while waiting or when the bus finally arrived. There was not a long wait at the pier, but Xpress pass or Concierge class didn't make any difference at all. Loved being greeted with champagne as we boarded and being shown to our cabin.
Cabin: The cabin was gorgeous-plenty of room, large bathroom (nice to be able to turn around in the shower!). The bed was very comfortable. The balcony was adequate in size and had comfortable chairs. The cabin showed no wear at all. The steward and his assistant kept the cabin in immaculate condition. The refrigerator was well-stocked but the items were ridiculously expensive. Towels were rough and not absorbent. I think the Concierge Class cabin was worth it. Priority luggage delivery didn't happen. The cabin steward was attentive without being overbearing. You could hear pretty much everything going on in the hallway but little from adjoining cabins.
