Shortening your stay with us within 7 days makes the reservation extremely difficult to re fill again. We are a destination town, booked months in advance. Last minute reservations are not common as vacations to Yellowstone are rarely planned at the last minute. Shortening or making changes to your reservation within 7 days of the original arrival date is not permitted. This includes shortening your stay at check-in or any time during your stay with us. Shortening your original reservation with us more than 7 days prior to arrival will result in a 15% cancellation fee for each night shortened. Please let us know if you need to change your dates.
