I was the Immigration Officer in Skagway in 1975.  We had 3 cruise ships each WEEK and they were much smaller.
Roy R.  was the only National Park Ranger in Skagway and he slept on the floor of the empty before remodeled Nat'l Park bldg. pictured at the beginning.  To go from that to now is amazing.  Many people are now given the opportunity to visit historic Skagway.
