I'll get attacked for this one! Many, many people use the mug year after year. No one seems to care. There may be an official policy, but unofficially, old mugs, as well as mugs from Wilderness Lodge, seem to be welcomed at the beverage serving areas. I'm not going to say what I do but I bet I know what you do if you have an older mug! Hey, what's a few pennies worth of beverages going to do to Disney's bottom line? I've yet to find a motel that doesn't offer free coffee to guests, and most offer breakfast.
