Are there any specialty bars onboard?
Carnival has several choice signature bars sprinkled across its fleet (note that bars vary by ship). The poolside, island-themed RedFrog Rum Bar features Carnival's own ThirstyFrog Red microbrew, as well as several other bottled beers and specialty mixed drinks, with an emphasis on Caribbean-based rums. The BlueIguana Tequila Bar doles out Mexican-inspired concoctions like margaritas and slushy tequila drinks, along with Mexican cervezas. At the popular Alchemy Bar, bartenders in white lab coats concoct vintage-themed "prescription" drinks for various "ailments." Handcrafted Cuban-styled cocktails, like mojitos, are on the menu at the Havana Bar, aboard Vista and Sunshine. Beer lovers might flock to the RedFrog Pub, a Key West-fashioned watering hole (bonus: aboard Carnival Vista, the RedFrog Pub comes with an adjacent on-ship brewery). Sports bars are present on many ships, and there are sing-along piano bars fleetwide, too.
