They will eventually. Remember when the only did G rated movies.. that slowly changed. Remember when no facial hair was allowed... that changed. The lure of money will eventually be to great and Disney will go for it at some point. I don't expect they will be setting up slot machines on Main Street in MK, but I would bet eventually they will offer gaming. If Florida were to legalize gambling then I would expect Universal to start it in their City Walk and just to keep up Disney would offer it in the Disney Springs. It will happen at some point, but will be more dependent on when states legalize it.I write this not as a joke. I love WDW, but I will say that over the past 20 years or so it seems to have gone out of it's way to cater to older visitors. I have mixed feeling I like a good drink in a relaxed atmosphere, but it's not something I shoot for while riding rides with the kids. Sometimes it seems like putting in a new restaurant or bar trumps focusing on putting in better entertainment and attractions(see fantasyland). I see that AK is still working on Pandora and several other areas but hey here are is a high end restaurant and bar!
I guess I just wonder, could we see them decide that a casino would be good for park goers? It's a revenue stream right, and with states constantly making gambling easier and more accessible is it something we could see in a decade or two?
