I booked on August 8th, and since then have had my backpack, which I'm taking as a carry-on, open in my spare bedroom. I throw lots of little odds and ends in here, like travel-sized toiletries, etc, so that I won't forget them. About a week before I leave I take out my suitcases to let them air out, and my mom will wash my clothes during that week. I'll actually pack the day before I go, but I'll already know exactly what I'm taking, it's just a matter of putting it away! I love to pack, and since I'm leaving January 3rd this year, I might pack a few days earlier so I won't have to pack exhausted from all the festivities.
