The main airport in the region is the Salt Lake City International Airport. However, there is a smaller airport in Provo. It is worth checking if you can fly directly to Provo.
There is a train, called the Front Runner, that passes through downtown Salt Lake City and goes all the way to Provo. This is a good, and affordable, option to commute from Salt Lake City to Provo. The Green line can take you from the airport to the Front Runner station at Salt Lake City.
There are several hotels in Provo. We recommend staying in the Downtown Provo area as you will be closer to several restaurants and the Provo Library. Some options are the Hyatt Place Provo and the Provo Mariott Hotel.
