I've been reading about theme nights on the RCCL cruises? How do you know ahead of time what the nights will be so you can take things? Does it come with your cruise documents? We are on the Explorer in March.
I was on the Explorer last May but never noticed an official "Theme Nights". One night I think they might have dubbed it Hawaiian Shirt & Western Night but I didn't see much. If you email RCCL from their website you can ask them if they know if any themes nights on your cruise and also ask them who & what the entertainment wil be.
