I'm not sure if this is etiquette related, per se, but you guys give great advice and I want the harshest critics possible to make sure I'm doing everything as respectfully as possible in regards to my guests.
My ceremony and reception site are both in a downtown of a city and they are about .8 miles apart - just far enough that it's not really walkable for guests in heels and fancy outfits. In addition my wedding is on a holiday weekend AND we share a weekend with a huge anime convention that takes over the city. The chapel has a dedicated parking lot, but the reception venue is street and garage parking. Luckily, street is free on weekends and garage is free after 7 so my guests don't have to pay for parking, but I worry we may be competing with everyone else for spots. There are two garages .3 miles from my reception venue for people to park in.
That said, I would like to offer a shuttle option so that my guests don't have to worry about finding parking, walking, or driving after drinking (our local PD is vigilant.) I can't really afford to shuttle guests from hotel to ceremony to reception and back to hotel. Would it be acceptable to ask guests to drive back to their hotel (1 mile from ceremony) to catch a shuttle? Of course, anyone who'd rather drive would be welcome to and cocktail hour would be ready when the first person arrived. Am I overlooking a better option? Should I make room in my budget to shuttle people to and from both venues? Would you take advantage of the shuttle option or drive yourself?
