He wants to go up the Shard too Rusty, but doing both would be a bit expensive for one visit. The London Eye trip (with the coach company) includes a Thames river journey to Westminster from Tower Pier (last time I was horribly seasick) but I can take Stugeron tablets and brave it out. He absolutely adores London, and I'm happy to go with him.
It's reassuring that the Eye goes quite slowly - I had visions of it positively whizzing round.
As a little girl, my parents kindly paid for me to go on a miniature ferris wheel for children. I was sick immediately, and it flew round and landed on several children in the seats below. And on a bus, I was once sick down the neck of the man in front. I was sick anywhere!
