We did a back to back boarding on Aug 10th, 2014 These were our 29th & 30th cruises (24 on Princess) and the first on Celebrity. For those reading this review I will try to make a comparison. I'm sure others have different opinions but theses were our feelings.
Pros: 1) Beautiful ship -.loved the balcony flooring and the bathroom
2) Friendliest crew of any of our cruises - they all seemed happy and to get along well
Rooms- Veranda 8268 and 8229 , we prefer the couch to be next to the sliding door rather than the bed AC/heating - in room 8268 you could not sit on the couch because the air blew directly down on you. We had to have the room steward and plumber come on several occasions because the toilet in 8229 would not flush - of course they thought I didn't know how to operate the flushing mechanism. The 3rd day the plumber did say someone on deck 10 had thrown something down the toilet and plugged all the system on the decks below that morning...once this problem was fixed the toilet worked the rest of the cruise. The couch is a nice touch vs. none in the Princess balcony cabins but it was so hard I had to bring in a deck chair if I was going to sit for any time. I loved the balcony flooring and the bathroom
