Continuing the conversation on the bonus question. Don't want to spoil it for people who haven't tried it yet.
Sad to miss this at Inspire I must have been doing a different session (So much good stuff, FOMO kicking in! Looking forward to Amsterdam in 2020).
I had a lovely view of Tower bridge from my hotel room that went someway to justify the £240 per night price tag.
I even risked dangling my phone out of the crack in the window to try and get a decent photo, failed but didn't drop the phone so that was a bonus. Didn't see the bridge lift even once though.
Anyway very enjoyable challenge, glad to have the target answers I would have struggled to understand what the challenge was looking for without them.
