we told the kids in dribs and drabs... like we're thinking of it... help me convince daddy... wouldn't it be fun if... etc... and finally we told them it was 'real' and we were going at the end of the month... now that we're only a few days out, we told them we are leaving tuesday of next week but we're really leaving monday... so, rather than have them wide awake all sunday night in anticipation, they will sleep well and we'll wake 'em at 4am and ask if they want to go a day early and if so, get up and get in the van... and off we'll go for our 7am flight!!
