UK Air Traffic control issues and EasyJet flight tomorrow

I’ve got the return leg of my EasyJet flight returning from Amsterdam to Birmingham, UK for tomorrow. I’m hoping it won’t get cancelled but if it does get cancelled, what are my options? If I have to stay a night, how much is reasonable for a hotel room for food etc.? I’ve got my car parked at the car park in Birmingham so unfortunately I have to fly back there.
