If you should happen to find yourself there during this time of year, do NOT, I repeat NOT, go into any Men's restroom wearing a red shirt.
A buddy of mine happened to be there 3 years ago for a conference and discovered that the red shirt is "their signal."
Yeah, he still has the green shirt he bought at Disney that day...
Their signal? If you wear a red shirt they immediatly insert themselves into your unholiest of places?
I would have bought the green shirt,no matter the cost.
