9. Punchliner Comedy Club

Stand-up comedy shows take place in a proper lounge, with comfy chairs and tables, and drink service, too. Carnival ships host four comedy acts every night — two all-ages performances and two late-night shows for the grown-ups. Just trust us: Some of the comedians get rather blue with their acts, so choose your set wisely. We’ve sat at a table of grannies as the comedy gets crasser — and funnier — and we can assure you we blushed harder than they did.
