Monica:
Sounds like you experienced a Fireworks Cruise! There are are so many
Specialty Cruises at Disney, I'd recommend calling 407-939-7529 and giving them your dates, your party size and seeing what they can cook up for you! When I looked into them, the cost started about $275 plus tax.
You might be interested to know that since your last visit, there are now cruises that you can enjoy where you simply buy an individual seat, rather than booking the entire boat. One such cruise is Disney's
Pirates & Pals Voyage, which may be more affordable if there are only a few in your party (and certainly more fun if you've got young boys in your family!) I don't know what part we liked the most when we went last November, the sugar fest
before the cruise where we ate as much cotton candy, trail mix and other goodies as our dentist would allow or meeting Peter Pan after the cruise. (Personally, I cried at how spectacular the fireworks were from the vantage point of the water....it was beautiful). When we go again in the fall, we plan a repeat!
Wishing y'all magical vacation!
