yes, they do have a pretty cool Pirate cruise, my daughter loved it when she went a few years ago.

Disney's Pirate Adventure
Aspiring buccaneers between the ages of 4 and 12 board a pirate-themed boat and scour the waterways around Walt Disney World Resort in search of pirate treasure during a swashbuckling high-seas adventure.
On this guided expedition, each participant enjoys a light snack and beverage, learns how to talk like a pirate, visits legendary ports-of-call, and—if he or she is lucky—returns with a bag of pirate booty! Disney's Pirate Adventure is a 2-hour sailing voyage that takes place each day at select Walt Disney World Resort hotels from 9:30 a.m. to 11:30 a.m.
