Okay thanks for the feedback, I had a quick ring around and for those that are interested here is the situation.
Annupuri - Snowscoot on all courses except Gondola
Niseko Village - Snowscoot on Banzai & Community courses only
Grand-Hirafu - Snowscoot on all courses except Gondola
Hanazono - Not sure (non english speaking operator)
Rustsu - Snow Scoot on all courses
Tiene-Sapporo - Snow Scoot on Rainbow & Paradise Grand courses
So it seems to me Snowscoot is widely excepted at most if not all resorts, some limit access to certain courses.
