When to tell the kids we're going to Disney

From the day we tell them to wheels down in Orlando, I expect a non-stop stream of “How much longer?”

I’d expect even the 6 year old to be able to make sense of a calendar.

If we tell them today, the youngest will probably gnaw a hole in the wall by July in frustration, and the 8 year old will have her hair fall out from stress.

Ah, special-needs children. You should have mentioned this in the OP.
