That may be, but I'm not sure if I'm willing to try my luck. The old hotel had plenty of experience with gamer/anime/furry conventions so I would imagine dealing with awkward but yet chill neckbeards was a calming experience (like you have stated, MF attendants were pretty well behaved).
Than again there is no point in worrying at this point, if it's good then that's great but if it's shit then MF3 will happen at a different hotel.
