Update: Dry run was a HUGE success.
Everything is in order for Sat.
On top of that, Mark showed me a side access double door to the gym. Sellers will have about 10 feet to walk from car trunk to the inside of the gym. No steps. (So park on Grand)
Also, he said the Grand parking is normally all empty on the weekend, and Susie and I picked up 6 "no parking" signs from the police station to scare off any attempts.
(There are lots of power outlets, but don't forget your extension cords)
I feel tired but not stressed any longer. All smooth sailing....

PS. We have a full crew for Sat, but if you were on the fence about selling, let me know asap. We can still accommodate a couple more tables.
