Hotel Accommodations

Information on the main and overflow hotel is included below. While you may use any hotel in the area, we will only provide shuttle service from Union Station and Hilton Ballpark to events such as the conference party. If you're at a nearby hotel, please feel free to use the shuttles too!

Other options

Generally any hotel search site can be used to find nearby hotels in downtown St. Louis at comparable rates. If you are flying in, it's easiest to find a hotel close to the St. Louis Metrolink light rail, which runs from the airport to downtown St. Louis and has stops near the conference venues.

Other hotels in close walking distance include include: Drury Inn, Pear Tree Inn, Courtyard by Marriott Downtown West, and the St. Louis City Center Hotel.

Venue

The conference will be held at the historic Union Station. Union Station was once one of the largest railroad stations in the world, and is now a hotel and conference space, with destination amenities like an aquarium, Ferris wheel, and restaurants.
