Is there any sort of firm rule about leaving European airports when there's a long wait for a connecting flight? We don't much fancy sitting around Weeze for six hours waiting for our home flight to Stansted.
I'm guessing it depends if you're in a transit lounge or not, if you are then once you leave you'll most likely have to faff around checking in again. I know this is the case in other countries but not sure about europe
if you have a boarding pass you can leave but will have to go through security and passport control to get back air side for your flight as the UK isn't part of Schengen.
