I posted this earlier, I hope no one minds me posting it again. As you can see, there's one Formal and one Semi-Formal. As for Pirate Night, at dinner they give you a bandana, and some people just have this or nothing at all, others just wear a t-shirt with a pirate pic on it, and others go all out and wear pirate costumes. It's really up to you, there's a good mix of everything. Formal night most people are dressed up - although some more formal then others - it's really fine either way.
