I'll be going on Saturday.
I suppose bathrooms aren't so bad. There are some more remote areas of the Convention Center where they have some larger handicap stalls. Off the top of my head, the west entrance by the escalators is almost always empty. I'll have two "handlers" going with me to help me get in and out, so that should be plenty of room. I can't believe I didn't think of the bathrooms...I guess I just thought of the crowded ones near the main halls and wrote them off.
