Shall we explain it before or after stepping past a couple of men smoking each other off?
Is this actual, or just wishful thinking on your part? Florida, Texas and pretty much every state in the USA have laws on the books prohibiting this. Have you been to a 'Gay Day'? No insult intended, as I have not, but maybe you have. From the posts I have read at the various Disney sites, those who have accidentally planned their family vacations during these 'Gay Days' have stated that unless they knew it was Gay day, they wouldn't have known it.
If it's two heterosexuals having sex, or two gay people having sex in public; you can bet that Disney security will be there to stop it, and press charges. Disney invests millions of dollars to promote a family friendly atmosphere, and they are not going to tolerate a gay orgy in the park.
