The woman cleared her throat.  "Please be advised you are portkeying into a muggle space, though no muggles should be in attendance when you arrive.  Your keys will also be used for the rooms you’re staying in at the hotel.  Please do not lose them.  Please keep your wand away as these are time sensitive portkeys and will be triggering in the next thirty seconds.  Your return travel will be facilitated by MACUSA.  We at the Ministry do hope you have a pleasant trip."  Her smile was tired and forced.
