I’ve been there a few times so I have a little insight. Venue – it is an old Sport’s Authority store. 2 stories, but the entire exhibit is downstairs. There IS an elevator, but I don’t believe there is anything upstairs except for Evening lecture. It takes less than 1 hour to do 1 loop if you check everything out. The venue is ADA Compliant, however I cannot believe there is ANY reason to go upstairs to an empty lecture room.
Hope this helped.
