MHO about Pirates is that it is great for kids. As adults it is not very exciting. However, get into it, chant, shout, stomp your feet, get into the spirit of it and you WILL have fun! Arghh.. (that's an order from the Pirate Captain!!)
Food is mediocre, but I recommend getting there early for the pre-show - they hand out appetizers which are more palatable...
I would not go there as just adults, but with the kids and getting into the spirit of it, we had fun. Can't remember where we got our tickets. I searched on the internet and picked them up that day. Of course, when you get there, they try and sell you add ons such as fron't row seats (where your kids are more likely to get involved in the show).
