Transportation for guests

What about uber vouchers? Then people don't have to wait on the bus, you have less chance of motion sickness, etc. Also, if it's a 10 minute drive in traffic, would it then be considered walking distance? Because you may have some people who decide to just walk depending on their shoes

I might be the odd one out, but its not my responsibility to get my guests to and from my wedding. Out of town guests will be renting cars and in town guests have their own cars. Why should I have an extra expense?

I've been to several weddings that used school buses and it was great - everyone fit comfortably. I was also at a wedding that had a shuttle disaster where a large chunk of family almost missed the ceremony because the shuttle didn't come, and we wound up squished on the floor of the bridal limo to make it in time. We're using them because it's the most cost-effective option to fit a large number of people.

The last wedding I went to had charter busses running to the venue and back, but I think busses of any kind would be fine. One thing to make sure of (which sounds like it won't be an issue for you due to your location) is that guests have transportation back, and know when a shuttle is leaving. At this last wedding there were supposed to be two shuttle trips from the venue to the hotel, but the road wasn't within eyesight and they didn't announce it, so we didn't see the first one come, and then the second one got stuck in a ditch on the way there and never showed up. We were kind of in the middle of nowhere where there were no Ubers or Lyfts, and we ended up convincing an inebriated groomsmen to let someone sober drive his car to make a couple trips back to the hotel.
