Second contract question

Okay, follow up question to my last contract question lol. I have found what is the perfect venue for us. But given our previous bad experiences with places like this and contracts, plus the fact we are still in a pandemic, I want to make surw my contract is clear and rock solid. The coordinator at this venue said she was willing to negotiate the contract, put in a cancellation/refund clause for Covid, but there is another clause that’s so vague and basically says they can cancel for any reason under the sun as long as we receive our deposit back. But it is worded so badly and is very open to interpretation if something were to go wrong. So I am currently trying to get her to amend it but here are my questions: 1. how long would you argue with a venue over a contract? When does it stop being worth it? 2. If they cancel, I get my money back or else they are liable to pay extra damages. But do I need to put in the contract that if they cancel, I am not liable for the rest of the money I would have owed? 3. Orrrr am i overreacting and should just sign and risk it? The deposit I would be risking is very small and the full payment isn’t due til 10 days before the event. This is literally my PERFECT venue and I am afraid we will not find another one that has the amenities/price that we need.
