We're only going to Switzerland but I'm thinking about starting to stock up on things to take with us. Would you bother buying big quantities of particular items that your family use like toiletries? Or that particular brand of cereal that only ds2 will eat? 
I'm also wondering how we're physically going to manage to move into our new house with 3 young dc's and no idea what to do with them when the removal men arrive with all our stuff. Last time we moved 2 dc's were in school and dh took ds3 to my mum's while I supervised the removal men and unpacked - not an option this time and I don't want to spend a fortune on a hotel for 5 of us when we arrive.
