This will almost certainly be ATC/weather (the incoming 716 was also cancelled). You'll have no problem booking something half decent in town at whatever the going rate is. You might want to keep a screenshot of whatever booking app your using to show that you weren't splashing out needlessly. Plenty of decent places around £250-300 tonight. Make sure to head to Sternen Grill in Bellevue for Bratwurscht tomorrow.
