I'm not sure why they would give your deposit because you are a non-profit. Does the room reservation not require a fee?
Tbh I'm not sure... The addition of a deposit is a relatively recent thing... (Probably since the owners became more hands-on with running the business.) I would ask them if they would refund it to non-profits, or have a reduced rate... they might refund it, or they might not, but you'll never know till you ask.
