So we chose the following day/times.

Thursday 5-8 Vendor load in. This seemed to work really well.

Friday 8AM-10PM. This was a bust. For next year, I am thinking 5PM-10/12? If I do that, vendors can load in that day/morning.

Saturday 8AM-10PM, worked fine, maybe even stretch it to 12?

Sunday 8AM-2PM. We ended up closing at 12PM. Maybe 8AM-12PM and its kind of a shopping day.
