I have filled my covered journal and have started a new one for 2016.
Began 2011 with a trip to Europe and finishing with a holiday soon in Korea/Hong Kong and a Moselle River cruise later this year.
It's great to look back on the pages which are filled with information on accommodation, tours, general info, airline/train timetables info etc.
My green one is rather battered as it has accompanied us on all our trips since 2011 and can tell a few stories on our adventures.
I write everything travel in them and would be lost if I didn't take it with me.
