For trips to Bali I buy a Marcia Lippman (photographer) Bali Journal, just a blank with lines spiral-bound journal. Available at amazon.com. I get a nice set of about 6 gel pens. I make notes about all sorts of things, like daily activities, how much each spa charges, restaurants, hotels I go look at, Balinese vocabulary, etc. I collect everything, especially hotel spa and brochures, museum flyers, etc. I put it all in a box when I get home and haul it all out when I need a Bali fix or when I'm planning the next trip. Pulled out a laundry ticket (the price list) from my favorite laundry to check prices last nite, all items run 5 cents to a top of 20 cents for a nitegown. Thanks for the glue stick hint, easy to pack along and will fit in the ziplock bag with the journal and gel pens.
