Any hotel and Airbnb in Sheridan, and then Buffalo, Wyoming is 30 minutes away but only 20 minutes from the reception location. If I were you, I would stay in Sheridan because Sheridan is the best. ;)

Since the chapel in Ucross only holds at max, 30 people we are keeping that VERY small. We will meet you all at the reception location following the ceremony. 8 Buckingham Road in Banner, Wyoming. You will need to Google "The Tunnel Inn" in Banner/Story, Wyoming. Park in the parking lot and people will shuttle you to the family cabin. We want to be able to share a bit of the ceremony with you at the reception since you won't be there in person. The officiant will say a few words at the reception so you don't miss out on too much! The reception will have heavy hors' d'oeuvres, drinks, music, and a dance floor!

However the heck you want to! :) But most people will be dressed up. We care more that you're here with us than what you'll be wearing.
