We have hidden all the snacks and all the travel games and books etc they are all in a different area that can be packed in the car when I get home from work at 11 the night before without any of them knowing. We are also going to put the rooftop carrier on a couple weeks early so they don't think anything strang by seeing it there a day or 2 before we leave. We will just tell them it is there for when they go to Algonquin park camping.
