Alcohol is still a big no no for carryon. Another snag we hit on RCCL...my husband had forgotten that he his little pocket knife in his pants pocket...RCCL security pulled him over, took the knife, give him a receipt so he could pick it up after our cruise. We're weren't the only ones being pulled over either...so maybe in that regard restrictions are a little tighter.
We've cruised before and never have had that happen...that's why we didn't even think of it. Lesson learned.
I carry ALL my make-up, and necessaries, like tweezers etc. and have never had problems. In fact if you run out of these things you can purchase them on board...so their not worried.
