Flight
Idaho doesn't have a lot of Airports. Luckily you're going to be close to the biggest one! The Boise International Airport (BOI) is best for flights! The airport is a quick Uber ride from many hotels near downtown Boise.
Travel Note
Boise has a lot of hotel chains located in convenient places. Places near the airport are recommended because they are about as close as you can get to the venue. There is a hotel in Idaho City, but hotels in Boise are only about an hour away! Hotels in Meridian and Boise are recommended, particularly if they are close to the interstate I-84 (Veteran's Memorial Highway).
