This way you could also pin the hotel keys on the map

I've been bringing travel ephemera home for years (not my random ORD-LGA boarding passes, but BPs from unusual -- to me -- routes or airlines, tram tickets and pub coasters from obscure places, etc.) and this is exactly what we do -- stick them up surrounding our big world map with pins in it.
