The best extra magic kindness we ever received at WDW was on our first trip with our kids. We left the resort on our first full day there, all geared up for Donald's Safari Breakfast, and forgot our camera. I was nearly in tears when we pulled up to AK and realized we'd left it behind. My DBIL offered to go back and get it while we went ahead to our ADR. A CM saw him heading back to the AKV bus stop, which no doubt looked odd at 7:30-ish in the morning, and asked if he had a problem. When the CM heard the story, he flagged down a bus that took my DBIL straight back to AKV. The whole round-trip excursion took maybe 30 minutes and he was back in time for us to take pics with all the characters as they came around.
If you could be on a WDW attraction right this second, where would you be? Not necessarily your favorite attraction, but what would make you happiest right now.
