I've done some searching and haven't found much on celebrity. They seem to be the 'worst' line to work for according to some, but that seems to be because of their rules.<...>
I didn't want to say anything, but now that you mention it, I wouldn't take another gig with Celebrity unless they paid me huge sums of money (enough to retire on).
It isn't so much the rules, as the attitude.
First example. We had all our gear (PA, horns, guitars, speakers, etc.) on a palette ready to load on the ship. They were loading stuff in waterproof containers and it started to rain. I politely asked the supervisor if he could load our gear since it could be damaged by water, and he immediately started yelling at me and refused. I had to find the cruise director, who found the musician's supervisor, who got in a shouting match with him and finally got our gear on board.
Getting off was almost as bad. They didn't want to unload our gear, as they were doing other things. I called the musician's manager again, and he told them we would be paid an extra week out of the loading supervisor's salary if we didn't get off before the ship left.
Each department is a different fiefdom and instead of cooperating with each other, they treat each other department with animosity.
They fed the crew leftovers (Carnival fed us passenger food in our own dining room). They interrupt your day and your port time with mandatory classes (nothing against the classes, but they should be scheduled with respect to the musician's time). And generally they treat you without respect.
In contrast, Carnival was the opposite. They appreciated what we did, treated us with respect, fed us good food, and basically left us alone as long as we did our job. The rules were simple, don't go into passenger's cabins, don't go in the casino, if you are using a facility (like a bar stool) and there are no open ones left for a passenger to enjoy (paying customer) you are expected to give up the facility for the passenger.
Celebrity won't be torture, but it won't be as much fun as any other line. Take things with a grain of salt.
As far as practicing. Each ship is different. The other musicians will tell you when and where the best times are.
