The wedding will be held in Estes Park, Colorado at the Della Terra Mountain Chateau.
If you are looking at any Airbnb or Homeaway I would suggest looking in either Glen Haven or Allenspark. They are about a 30 min drive to the Della Terra. Also Homeaway does seem to have more rental properties available in the area than Airbnb.
*Note, if you are planning on staying in Grand Lake, Colorado just know that if US Highway 34 is open then it's about an hour and 40 min drive to the Della Terra. But if that highway is closed due to weather then it is about a 3 1/2 hour drive to the Della Terra.
