We cruised to Alaska with Celebrity in 2014. Had a great time, both in port AND on the ship. I would disagree with some who say it’s “all about the ports.” The ship and the vibe, the food quality, the room quality, all of it are important to us as well as the ports.
We liked that cruise so much that we’re going again this June, same room, different S-class ship, almost same itinerary. We’re in our 40’s now.
