No, the OP states in his OP that he's got a connection to DXB at 8pm. On this basis, do you accept that what he's wanting to do is no different to what you've done in the past? (That's not confrontational btw, I just want to see if I'm reading this correctly).

As for the "rules" - i'd be interested in the definitive answer here if someone from the airport side of things can provide it.
