I am not the show promoter but I will try to help.
Show up early? Yes. Show up anytime you want
Sleep at fairgrounds. No, from what I have seen in the past.
Bathrooms
I dont know the cost, Andy or AAron can help you there.
I think you prepay. That way they dont save a spot for someone that doesnt show up
Normally spots are inside and out as it was in the spring. The fall show is all outside from the advertising i saw
Should be rain or shine
