I thoroughly recommend taking the Harwich, Hook route for a ski trip.
Overnight on Thursday, then drive all day Friday without being under any pressure and stop in a hotel just short of the resort. Then up early on Saturday and on the snow at 09:00.. Check in at the end of the day skiing. Reverse on the next Saturday, check out early, ski all day and stop overnight close to the resort, Drive to Hook in a leisurely way and overnight to Harwich on Sunday night. A relaxing evening meal and bed on board then off the ship at Harwich at 08:00.
Brilliant and evocative. Much of what is shown had hardly changed in the '50s, and even early '60s. I never did the Harwich trip but we did Dover-Calais several times when skiing. The difference here is that we didn't bask on deck but sheltered in a cabin. My mother was averse to the sea, having travelled from Japan as a child of English parents, and insisted on having a cabin, where she prepared herself with a double brandy.
Many of the clothes were hardly changed after the war. What is very evident from the film is how organised life was then. We have an idea nowadays that we have advanced, but see how well-dressed pepole are in London and how tidy the streets, with not a trace of chewing gum or litter, although the city was almost as populous as now. These were, of course, middle class folk, but there were a lot of them.
A friend of mine, long deceased, was the Chief Engineer on one of the LNER boats. He told me that one foggy night he discovered that there appeared to be a lot of sand in the calorifer so he rang the bridge and suggested to the skipper that they might be aground! They were! Journeys were not all as smooth as in the film!
Later, on war service,he was torpedoed off Indonesia and spent 3 weeks in a lifeboat until rescued by RAN destroyer Quiberon. He named his Firefly racing Dinghy after her. He said Quiberon was the finest vessel he ever saw.
There is a similar one , about London only, from 1933. It looks to me as if the cars and general hardware are more old-fashioned, even though there are only a few years difference.
