I honestly hope this won’t come off sounding very cold, but I’m wondering what there is to do. I’m not from Chicago, and I know very little about the community in general but this is the way I see it. No one specifically planned that the cheaper hall would need repairs. Now that the more expensive one is the other option are they now supposed to lower their prices for the customers? For various reasons, thats not really practical. As for the idea, is there any area where its possible to do something temporary? Even a tent?! I understand where you’re coming from but this is something that could be solved with a some creativity.
One more thing, if there is any problem in Klal Yisrael, B”H its something like this.
