This class is being hosted in Duluth, Minnesota. If flying you can fly into Duluth (DLH) or Minneapolis/St. Paul (MSP) which is 2 hours south or Duluth.
Lodging to check would be Tru by Hilton, Days Inn by Wyndham is close, but you will have to read reviews of the motel. It has been there forever and I have no idea what it is like. Country Inn and Suites by Raddison is closest to the airport. The Canal Park area is the hotspot to stay, but also the highest rates.
