Their website, found here, allows you to book online. Note that reservations are required and as it is a popular shuttle, they are considered necessary to guarantee a spot on their shuttle.
Groome travels from Atlanta’s Hartsfield-Jackson Airport and conveniently drops off at our Auburn University hotel. Their shuttles run from the airport from 5:30 am through 1:30 am and to the airport from 1:10 am to 9:10 pm with a shuttle departing every hour and fifteen minutes between these times, meaning there is almost always a shuttle conveniently timed for your travel.
