Okay, while we're still on the topic, I have to add one in from our trip in 1998. We were at the MK in December on a Saturday, while they were taping the ABC Christmas parade. Of course the place was packed. We got a spot for the parade early, and since one of my sons was asleep in the stroller, DH volunteered to stay with him and hold our spot while I took the other 2 in the stores behind us on Main Street.
Well, we're in the first store, my oldest son shows me something, and POOF, my 3 1/2 year old is gone. We look on our own for a couple minutes, then tell an employee. They sealed the exits (didn't know they did that) and quickly confirm that he isn't in the store and must have wandered out into the gaggle of zillions of people on Main Street.
They told me to go to Guest Relations and hopefully he would be brought there once he was found. So I went out to find DH and leave my other son with him. When I got there, he was with my youngest (the one who was lost) and a cast member. Apparently DS had found a cast member on his own, gone up to him and told him "I lost my Mom, AND my Dad, and BOTH my brothers!" (in a tone of voice that implied "can you believe that? BOTH brothers, not just one - the odds against that must be astronomical!") DH saw the cast member walking up Main Street with him (probably to Guest Relations) and claimed him and the cast member just had to tell DH what my son had told him! Of course it wasn't my son who'd gotten lost, he'd just misplaced the rest of us!
