This hotel is 5 minutes or less from our venue. We do not have a block of rooms, but these suites can be priced as low as $140/night when booked well in advance. They have accessible and pet friendly rooms. It is a 20 minute drive to the airport (unless traffic is bad since it's Bozeman).
If you would prefer to camp, this campground at the Bozeman Hot Springs is 10 minutes away from our venue. It offers tent camping, RV hookups, and small cabins. We are in their busy season, however, so these would need to be booked well in advance.
