Convenience is the specialty of the only hotel on the grounds of the Austin–Bergstrom International Airport. The donut-shaped building, originally built in the '60s as a U.S. Air Force base, features a central atrium, with a dome soaring above three balconied floors, and limestone pillars surrounding a lounge area. Rooms overlook either the atrium or outdoor pool. A 24-hour business center near the front desk allows guests to print airline boarding passes before check out. Free shuttles run to and from airport terminals and a $1.50 Airport Flyer bus services downtown.
