Ok it’s worth knowing that’s it’s feasible to leave, I’ll have to look into that, although I don’t particularly want to get a hotel as then I might as well have just bought a more expensive ticket.
other long layovers last year: Abu Dhabi and either Riyadh or Jeddah, can’t remember which Saudi one it was as I flew via one on the way there and there other on the way back. I think it was Riyadh though.
