No - there are no facilities there. You could come out by coach.
Thank you :)
However the preferred direction is coach TO Milford Sound & flight back - for 2 reasons:
#1. If the flight is cancelled you still can come out by bus
#2. The coaches do all their stops on the way in to MS & most of the passengers sleep all the way back.
You will miss so much if you fly in/bus out.
Best do it round the other way :)
