Rio debuted a new combo experience, the Carnival World & Seafood Buffet, which has a separate line of more than 70 seafood dishes added to Carnival World’s 200-dish-strong smorgasbord. How does it work? If you want more fun with fish, you’ll pay a $15 upgrade and get an invisible sea creature stamp on your hand. A buffet team member with a black light will check to make sure you have access to what kinda feels like Club Shrimp Scampi before you enter the roped-off area; When I went, I was asked to show off my glowing lobster mark to some non-English-speaking eaters who wanted in but didn’t understand.
