Disappointed with some the staff

Overall the experience was great.
The food on the ship was fantastic compared to the (fascination), which I cruised with last year.
The ship was good. I just wished the waterslide was better.
The stops were great and I had a great time. The only place I wouldn’t go back to is Belize.
The staff: Cruise director Nooman was great. Assistant director Cassidy (classy cassy) was terrible. She was not friendly at all and not funny.  Mario (my waiter) was great. I talked to him a lot and he went above and beyond his duties. Arnold (the guy who cleaned my room) was very friendly and seemed like really cared. He even found me a wine opener (something next to impossible to find in a ship when don’t want to pay a cork fee). I gave them a bigger tip knowing how hard they work for so little (I read in a book and the guy summarized his experience working for Carnival as a fun sweat shop(he was a waiter).
Entertainment: Shows: Very bad! Especially the Brits: I had to leave in the middle of it of how bad it was. The Comedians were great. All of them made me laugh very hard.
Good experience overall.
 

Was great. I have no complains.
