I just took this on a trip for my family of four and it worked great.  I was able to keep four passports, boarding passes, a few cards and some cash with room to spare.  Before I had a small pouch i would keep this stuff in and it never stayed organized and things fell out when i would pull the passports out.  My favorite part was the zipper behind the card holders, that was a great spot to stick the immigration papers we had to hold onto during the trip.
