We're taking my 2 older boys (6 & 8) in Dec. I know its too early, but trying to decide when would be a good time to tell them. Maybe 2 -3 weeks before? I'd love to completely surprise them, but my oldest has Aspergers and does not deal well with changes. He'll need to know all of the plans ahead of time to give him a chance to adjust. And I'd like to show him the maps before we go, so he doesn't fixate on them at the parks. I'd like their input on which rides & attractions, they want to do. So any advice on when to tell them or any creative ways of telling them?
