Packing-Spacebags

I did some packing this weekend. Diapers really take up alot of space. I am going to do some repacking Friday when I get home from my work trip. They look compact and Costco can fit 234 Huggies in a cube so why cant I get all of them and my clothes in a large suitcase. I was planning on using spacebags for the baby clothes and my clothes to try to pack more in there, but never thought of spacebags for diapers too. I will give it a try T! We may need to have one more carryon size bag but have been warned that the cars over there are smaller. J says to 'pack light' and I am trying, but there is so much I want to take to B and the other babies, hopefully the mobile will fit. There probably wont be anything in our suitcases when we come back. I will have to see what I can buy. Maybe we will wrap a box of diapers in paper and check it as luggage. Has anyone done that?
