Ahoy Jennifer! I've gone on the
Pirates & Pals Fireworks Voyage a few times now and love it more each time! It's fun for all ages, and provides one of the best viewing points for the Magic Kingdom fireworks. The snacks have varied each time, but typically include soft drinks, juices, coffee, tea and hot chocolate, and snacks like pretzels, brownies, chips, desserts and chocolate coins. The desserts at the Tomorrowland Dessert Party are amazing, and the focus of that event. If you are deciding between the two based on the food, then the Dessert Party is the one to choose. The Pirates and Pals voyage is more about the voyage, which includes great interactions with your pirate Patch, trivia games, meeting Captain Hook, Smee and another surprise guest, and the amazing fireworks. It does fill up, so be sure to book your voyage ahead of time by calling (407) WDW-PLAY (939-7529).
Hope this helps Jennifer!
