WOW! A hotel!
My parents liked to rough it. We went to 1930s-era vacation bungalows on a hillside overlooking Avalon on Catalina Island off the coast of California (1957 & 1958). No room service, no carpets, but it did have a rustic kitchen with a depression era refrigerator and a really scary shower in the bathroom.
The beach was rocky rather than sandy, but the glass-bottom boats and the the flying fish in the Channel were kinda cool.
To travel to Catalina Island we took a steamer that had wooden benches on the outside decks. I think the island had an airport but I could be wrong on that; flying boats is what I remember.
Once my Sister was old enough to travel, my parents settled on beautiful Glen Lake Michigan as our regular vacation spot. Cottages, Very spare cottages! A stunning lake, with the huge Sleeping Bear Sand Dunes in clear sight.
