Name this vehicle...we can't

My grandparents liked to travel, by car, in their younger years and this one is among the few photos I found, It is from the 1930s and I assume somewhere in the West where and when there was lots of snow, We don't know what type of bus this was but apparently it was used to bring visitors up to this hotel.

I am watching a 1933 movie, Mary Goodwin, MD and the bus going from a train station to a hotel is very similar in style to this one.
