NO! I see (27 year old) kids sleeping in strollers outside of It's a Small World every time we're there! You should check the stroller swaps for a double stroller- that way you can fit more than one. Or, just steal someone else's; they'll never know it was you & just think of all of the loot you'll get (Mickey Ears, BBB sashes, whirling flashy light things, and more)! The spoiled one year old that they belonged to won't know the difference.
BTW, my entire family (about 100 of us) will be at MK on Christmas Day & it's my cousin's uncle's daughter's son's girlfriend's hamster's birthday. Where should we eat? Will they put us all at the same table? Do the kids have to pay the kids' price? What about the hamsters?
