I usually collect the following for a trip into separate notes as the confirmations arrive in email or from the web:
Rental car reservation
Customer or contact address for where I am going
I format the title of the notes like this
2013.05.05.14:40-17:25 LH 1804 Munich - Madrid Booking ref XXXXX
2013.05.05.17:30 AVIS confirmation code XXXXX
2013.05.05.18:00 Hotel Nisequenisedonde confirmation XXXXX
2013.05.06 Meeting with my favourite customer
2013.05.06.19:00 Dinner at XXXXX with YYYYY
2013.05.07.12:10-14:45 LH1801 Madrid-Munich
The reason for the date/time format (yyyy.mm.dd.HH:mm) is so that they sort in chronological order when sorted by title. The times for the rental car are just estimates and keep the notes in the right order. Electronic boarding passes go in the same note as the e-tickets. Keeping the confirmation codes in the title means I don't usually have to open the note. The return flight note usually contains an Evernote link to the first flight that contains all the details.
I also tag these notes as "-Fixed Date" so I can view in list mode only those notes that have this specially formatted title. When the date has passed and I don't need them handy anymore, I remove the "-Fixed Date" tag.
Where needed, usually in the note with the hotel reservation, I put the address of where I am going into Google Maps and make a small-medium screenshot of the area with the address marked. More than one if it is complicated.
Now, here is the trick: In Google maps, select the "more" button just under the address, and select "send". The blue text is a link to Google maps that you can copy with right click. Then, select the map image you pasted into Evernote and type ctrl-k, ctrl-v to add the maps link to the image. Then you can open Google maps with the right address right from the note.
These "Fixed Date" notes are in a saved search so I can get to them quickly - the reason for preceding it with a hyphen is so it sorts to the top of the saved searches.
Hope this helps.
