Hey everyone. This will be my first year going to a convention of this size, and I have a tendency to get overstimulated sometimes. I can't find anywhere that mentions one and was wondering if there will be a low stimulation room/where I will be able to find it?

I believe that there is a Quiet Room.

Yep! I found the information for it from last year (room location and hours).

QUIET ROOM – 211Thursday – Saturday: 10 am – 6 pm Eastern
Sunday: 10 am – 3 pm Eastern
