I have seen this stated on the website on other holidays when we have been there (New Years, July 4h, Easter) but there never seems to be anything strictly stated or explained. I think some people improvise (bunny ears, red white and blue, etc...). Maybe go as a sexy pilgrim?

Over the last 4 years that we have been going, the themes have changed names but they are basically the same and easy to wear something appropriate to fit in. However, if you are trying to dress over the top specifically for each theme, I can understand the stress and not wanting to pack for the wrong thing. We have seen a few times when there was a confusion of theme nights and some were dressed one way and others another... No one really cared and it was no big deal to anyone. Don't stress too much over it.
