Might just hang about the airport
Things change I know and it's a looong time since I was there, but down in the depths of the airport there used to be a disco called "Dorian Grey". It ran pretty late in the good old days, certainly chucking-out time was Sunday morning. I got bitten in the knee by a dwarf there and also contracted SMD - Sudden Morning Deafness - dancing too close to the speakers in the fog. We all used to drive up from Darmstadt now and then for a bit of a rave
There was also a cinema and when they showed "The Life Of Brian" there was An Incident with some God-fearing travellers kicking up a fuss about blasphemy. And I got my leg stuck between two seats. Then they started showing hard-core pornography and nobody complained.
