We've done many cruises on Celebrity, including on the Reflection. We'll go again. Celebrity has a very good mix for people our age, retirees.
However, I can note that there have been no improvements that I can point out, and some significant detriments.
We've always like Bistro on Five, where fresh crepes are served (and sandwiches on other ships). We disliked the increasing price, which was $5 years ago. Not only was the priced raised, but Bistro on Five is no more. It is now Sushi on Five.
Our cabin had a partially obstructed view. This was our first time to try this, and it was no problem at all. You could see 100% of the view over a span of about 20% of the balcony. The other 80% was restricted by a lifeboat on the left, and a room that jutted out on deck 5. You could always see to the horizon though. It was not a problem, and we would do it again for the right price (as in this case).
Nicely developed port area, a big plus from the old days when the ship docked a half mile from the town.
Always fun shopping and wondering the old town, which is adjacent to the port.
Nothing special, and nothing near the port.
