I've decided that the Cunard cruising formula may not be for me... and glimpses of how things are on other cruise lines has reinforced this.
When we were docked next to a Tui ship, they had an entire fleet of e-bikes available to use. I'd have loved to try one, and would like more details about how it works. (e.g. what happens if it gets stolen while in your care!). Pic attached.
