I have sailed the Summit for five cruises this year. I thoroughly enjoy its two Southern Caribbean itineraries, and I appreciate the high quality and good value of these week-long cruises.
I posted a detailed review of this ship in January of this year (see elsewhere in this website), and I will not repeat myself except to say that the crew is as kind and helpful as ever, the officers still make an effort to meet the passengers, and the food in the main dining room is even better than before.
Perhaps because of the Caribbean itineraries, this cruise seems higher energy (with a higher decibel level) than most of Celebrity's other cruises. Perhaps because of recent beverage package promotions, there also seems to be more drinking than before.
