Do these videos prove Cunard has discovered the secret of time travel?

If you are thinking of booking a cruise on Cunard’s Queen Elizabeth, everything you ever need to know – and probably more – is set out in this instructive video.
How to tell the front of the ship from the back and port from starboard, where to enjoy afternoon tea, and how to book a shore excursion – it’s all here.
The film – some of which was shot while I was on board in April – gives the impression of being educational rather than an entertainment. It’s certainly nowhere near as much fun as the free-running tour of Thomson Dream, although presenter Rachel Pierman does provide a comprehensive compendium of helpful hints.
Watch carefully and you might even catch a glimpse of Mrs Greybeard enjoying dinner in the Verandah restaurant.
There’s a second film about Queen Victoria, rather unnervingly featuring interviews with some of the same people – entertainments director Amanda Reid and port presenter James Anderson-Smith, to name but two. They can’t be on both ships at the same time . . . or can they? Perhaps Cunard has discovered the secret of cruising through time.
