I recently designed a map to accompany some friends' wedding invitations, highlighting all the places important to them along the route. Hotspots included where they met, where the proposal took place, pivotal sportsgrounds (obviously), and department stores of disctinction - the place where it all started!

Guests are shown how to get from 'vows to venue' along the best route.  I imagine it forms some sort of Wacky Races-esque activity to break up the day, followed by a photo booth.
