Both conferences will be held at the Downtown Campus of the University at Buffalo. The University at Buffalo provides information on how to travel to Buffalo and the Downtown Campus.
There are many hotels within walking distance of the venue or via a short ride on the Buffalo Metro Rail. The Metro Rail stop for the conference is the Allen Allen/Medical Campus station.
There is no official hotel for ACAL 57 or Banto3d. The University at Buffalo regularly houses guests in two Downtown Hotels: The Wyndham Garden Buffalo Downtown, which is very close to the conference location, and the Hilton Garden Inn Buffalo Downtown. If you have questions about a specific hotel, please feel free to ask the conference organizers.
