I suggest you take your Hidden Mickey list with you to WDW, regardless of where you get it. This past August I stood in line at guest relations in MK for 20 minutes just to be told they did not have a "list" to hand out to guests. The CM said she was unaware of a printed list anywhere(must have been new). My youngest daughter and I walked over to the Contemporary and asked for one at the front desk. The CM even smiled when she handed it to us, and told us to have fun.
