Oh my goodness, whoever told you that?

I hope it wasn't one of us - if you can imagine our team having to escort all of our 100+ kids in each space to their individual parents- in pairs, of course - it simply would take far too much time/ we don't quite have enough of us to be able to! Not to mention it certainly wouldn't be safe (which is #1 for us on
DCL!).
The way we explain to guests what happens in an emergency - and what they really MUST do - is immediately head upstairs and collect them, where we'll be waiting with the kids and clipboards having divided them in half A-M, N-Z by last name. If you're on board during a crew drill, you'll be able to watch and see exactly how we do this!
That said, we DO bring the kids down if for whatever reason the parents don't show up to pick up the children and all the others have left. You can easily see what assembly station they're in- it's printed on their Mickey Band!
