There are some life experiences that need paper documenting. Things that you want to have a tactile experience with when you read and relive the memory of. The "Mini Book and Letter Hybrid" from Miniature Rhino seems well suited to documenting travel adventures. The back cover is a small envelope which would nicely store mementos and souvenirs from trips. Each book is 12 pages long; perfect for including all the pertinent details with a label on the front. Perfect.
