Please forgive me if this is a dumb question (I did try searching the forums first). This will be my first time at Gen Con and I have an event I'm signed up for (and have the ticket) that doesn't have a location listed. The event is "Dark Souls - Beastly Brushstrokes with Elizabeth Beckley Bradford." How might I figure out the location so I can best plan that part of my day?
Thanks for any help!

Surprising they haven't done it yet, it must be one of the few events without a location.  They will have to assign a location before the Con starts, just keep checking the event.

If you can't get it online, there are Event HQs scattered around, and they'll be able to help.  That doesn't really help you if you're trying in advance to plan your day.

Thanks so much! I mostly mean to plan loosely. I tried to only sign up for a few events a day with lots of gaps, so I think I should be fine.
I have a seminar before that, so worse comes to worse I just leave from that a bit early.

All the MHE events are in 101-103. There will be a table near the entrance where they can tell you which tables a specific event will be at.
