My sister is getting married in New Orleans in April. They made a deposit on a place and then cancelled a few months ago because of COVID. The event space said they couldn't return the deposit bc it was extremely unlikely that they'd be able to find another party for that day. Fast forward to this week, sister emailed the space to ask about using the rooftop for a small gathering. They said it was not available because another party had just booked it. My sister then asked, if given that it had been rebooked, their deposit could be returned. She received in return (what I saw as a condescending email) saying the deposit could still not be returned because the new booking was at a discounted rate and still wouldn't add up to the amount in my sister's original contract. I understand how much the industry is suffering, but given that they were able to re-book for the date in question, it doesn't seem reasonable for my sister to bear the brunt of the cost. For example, if you break a lease and then the landlord successfully rents the unit they cannot continue charging you (at least where I live in CA). Thoughts? How would you handle it?
