We usually need to take hotel confirmation, airline tickets, rental car confirmation, discount cards, etc. My husband always says I am disorganized when I go to find something in my bag. So, last year I went to Wal Mart and bought cheap, clear pencil pouches, all different colors. I used 1 for air and car, 1 for hotel, 1 for parks, 1 for cruise, etc. So when I need docs for the location I was at I only had to pull the right pouch and everything was there. I placed the pouches in my carry on and it worked quite well. Those are the only papers I brought, only docs needed, nothing else. Of course my disorganization played a part anyway, left 4- 2 way radios in the night stand at Royal Pacific (did get back) and also 2 Pittsburgh footballs, bought at the airport, which I didn't even realize I left on the top shelf of the closet at RP until football season started. But I always remember the important things, birth certificates and money. Everything else can be bought or done without.
