Yes, we have setup a shuttle service for pickup and drop off to and from the venue. Details can be found on the travel tab.
We do not recommend anyone relying on Uber or Lyft in Walla Walla since there is an extremely limited number of drivers. We suggest you stay at the hotels we have discounted rates at or Airbnbs within walking distance of the hotels so you'll be close to the ceremony, shuttles, and any activities downtown.
