Hi Benjamin!
Thank you for bringing your question to the Disney Parks Moms Panel!
I believe you are talking about the
Pirates and Pals Fireworks Voyage. According to the Walt Disney World website, you can "Hop aboard this wild voyage, ye brave buccaneer, and experience the tales, tunes and thrills of pirate life first-hand"!
All of this, PLUS snacks, drinks, fun characters, and a spectacular view of Wishes Nighttime Spectacular is the perfect way to spend an evening.
You can book your reservation by calling 407-WDW-PLAY (407-939-7529). These can be made up to 180 days in advance, so be sure to reserve early!
I hope this helps! Please let me know if you have any other questions.
