Flight
Salt Lake City is the closest large airport to fly into, and usually a lot cheaper than flying directly to Idaho Falls. It's about a 3 hour drive if you want to rent a car. Another easy option to get to Idaho Falls from here is the Salt Lake Express shuttle service. It runs every day and picks up at the SLC airport with several stops between there and IF.

Flight
For those wanting to fly directly into Idaho Falls, we have a regional airport in town. Most likely, you'll be connected from your location to IF either through Dallas, Denver, or Salt Lake City. Rental cars are available at the airport, and the city does have Uber and a small public transportation system called Greater Idaho Falls Transit (GIFT) available through an app.
Hotel
Probably the closest hotel to the venue in distance. Only a ten-minute walk across the lovely Snake River Greenbelt and through the edge of downtown.
