It's not going to happen. If Disney had to change Princess Jasmines costume because of disgusting (sober) pigs getting out of line, there is no way they would have Chance in an area were a bunch of drunk people can touch her. Heck, they had to remove Carrie from the scarezone last year because of this very reason! Not to mention the fact that this is HHN, not Mickey's Not So Scary. If you want a photo-op event, head down the street. It's no fun for anybody (actors or other guests) to see flashing camera lights going off all the time. At least Universal offers the Dining event now for people that MUST have pictures with the actors and hopefully the $50 upgrade keeps the pigs away so Chance is safe to roam the restaurant.
