First off, I am a Moleskine purist now that I've found them.
BUT I also REALLY love this notebook.
It has great amount of space for weekend, short, and long trips. I like the way that the space for writing gets longer the longer the travel time is. That means that weekends have the largest number of entries, and long trips have the least entries, but most recording space.
I like that there is a seperate section just for planning and for a travel wishlist.
The conversions are incredibly helpful, from travel times to clothing and weather charts. There are also spaces for card and travel information so that you have it all in one place.
If you like to travel, then this is the perfect notebook for you.
Now I just wish Moleskine would come out with a notebook of unspecified locale like their City Notebooks, with it concerning just a single trip, because I like traveling to little known or even large, but not main cities in a country.
