We have been cruising for 32 years. The first cruise was on NCL Southward which is long gone. We have heard that the service is wonderful on Celebrity and we wanted to try it. We have cruised with everyone of the major cruise lines except Celebrity and Holland America. Let me first say that this is my opinion and what I found not so fun, you may love.
First the good: The ship is clean and the staff is friendly and very accommodating to your experience. The food is a step above for the most part but we did not like Blu restaurant and found the wow factor missing with food and choices in that restaurant. The portions are controlled and you never over eat. The specialties restaurants were nice but again I have not been wowed in them. The Susi was not as good as I can get at home and Tuscany was good but not exceptional. The ship has all the same bread choices every day.
The buffet on pool deck was nice and I will say has many choices and good quality.
