For perhaps less than 800DKK total net out of pocket (for hotel
Night+roundtrip transport), a person could take the train from CPH to Sweden and stay at the Best Western or Quality View in Hyllie. I would do so when it means I could get 3.5+ hours of sleep in a bed that I wouldn't otherwise get for the day. But there is the small risk of the bridge closing down (at least in part) due to weather while the airport operations continue.
