There is a parking garage next to each of the downtown conference hotels. One is to the east of the Hilton Fort Wayne and is connected by a sky bridge to the Hilton and Grand Wayne Center. Another is on the south side of the Courtyard by Marriott and is connected to the hotel and to the Grand Wayne Center. If you park in the Courtyard's parking garage, it is probably faster to walk to the convention center than use the zigzagging sky bridge. The parking garages are shown in orange in the map above.
The Allen County Public Library has two surface lots, shown in yellow on the map. One is on the south side of the library and the other is on the east side. The library also has a parking garage with entrance on Wayne Street. The library's garage is only open during regular library hours.
All lots and parking garages around the Grand Wayne Center cost $7 for a full day.
