Parts of the ship were a little dated (i.e. TV in the stateroom, tiles in the stateroom bathroom, lower ceiling height etc.) but it was extremely well maintained. You could tell that there were efforts to modernize the ship. We had recently been on the Solstice, so there was much comparison to our previous trip.
It was very convenient leaving out of NJ, so we were able to save by only purchasing plane tickets from San Juan. We loved all of the ports (we did our own thing and spent very little at each port - see port reviews). There was a bit of motion, especially to and from Bermuda, but it was manageable. (Recommendation: Ginger pills - they are safe and super effective without the drowsy side effects).
The crew was SUPERB - absolutely no complaints. The food was excellent, although I thought that the buffet experience on the Solstice was much better (better and hotter food, better layout, I prefer to get my own food like on the Solstice rather than them serving it to you like on the Summit). However, the food and service in the dining room was perfect. We had Select Dining, as the earlier option was not available, but we went at 6pm and there was no wait to get seats.
Activities were fun, although I felt that they could be a bit varied (particularly, the guest speaker), and the shows were great (except the Comedian which is purely preference). All in all, great trip!
