We've sailed with Celebrity before. 21 days on the old Mercury through New Zealand and Australia; 14 nights on the new Solstice to the Caribbean; 14 nights round trip from Seattle to Alaska on the un-solsticized Infinity; and now 14 nights on the updated Summit. We won't judge future cruise selections on Celebrity based on this experience on the Summit.
First -- highlights were the great evening entertainment and the Celebrity Life lectures from the Kennedy Space Center and NASA. All were excellent. Celebrity is to be commended for continuing it's great stage presentations and for the variety of live entertainment throughout the ship.
The staff were very accommodating friendly. We were greeted by staff we had met on prior Celebrity cruises. Both Devon and Marlon in the aft bar on 10 remembered us from prior trips and were very service oriented even though their bar was often the wettest and coldest place on the whole ship as we travelled further north.
8177 in conceriege class toward the aft of the ship. Small stateroom and small balcony like other outside veranda rooms. Quiet location. Nothing special although the fresh fruit, flowers, and afternoon snacks are a perk. We wouldn't have paid extra for this room but were able to get it for a lower price than we originally paid for a veranda stateroom in mid ship.
