Hi ,
Me and a couple of mates are riding down to monaco from geneva in july 2020 on sports bikes  and we are looking for some info on the trip ... we arrive in geneva on a thursday and want to be in monaco for the friday late afternoon, so we are looking for some place to stay about 150 miles down  for the first night and then friday morning head down to monaco.
the (route des grand alps)  is that the best way and what sort of roads?
Many thanks
Jim
