I usually over pack for vacations. We don't go to DL very often but for our up coming trip (360 hours away) I decided as we can afford it this time, to pack the bare minimum and buy whatever we need there. That way there is lots of room in the suitcase for our souvenirs and gifts. One good piece of advise if you can pack everything into zip lock bags, wow does it make a difference to how much room you have left over in your suitcase!
