The way it's working out for our wedding, most of the guests will be from out of town. We just happen to live in an area away from most of our friends and family. *shrug* For this reason, many people aren't familiar with the area and even for the people who know it a little bit, it can be confusing. For this reason we are providing all of what they might need to know mapped out for all of the events of our wedding weekend. You could use mapquest or google maps but I actually found something much better than BOTH of those combined!
The service I recommend is called WeddingMapper.com. It's a mapping service specifically designed for occasions such as weddings. It allows you to put virtual markers (in fun little shapes, I might add) at all of the different important locations of the wedding (church/ceremony, reception, hotels, rehearsal dinner, even airports, etc.)
Here is a screen shot of our wedding map by Wedding Mapper:
The service can be hyperlinked to your wedding website OR (if you pay a little extra that's really not that expensive anyway) you can print actual full color copies of the maps off with every route and every location clearly marked.
I'm pretty sure that any location (in our outside of the US) is game since Wedding Mapper actually uses Google Maps to draft up their maps. It's great!!! And it's even more helpful when you've got a ton of guests coming in from out of town who aren't familiar with the area where the wedding will be. Also, as an added bonus, you can upload pictures of your actual locations to your map online so that when guests hover their mouse over the locations, actual pictures of the locations pop up!
