Platform 9 3/4
Platform 9 3/4 of King’s Cross Station is somewhat of a tourist trap for Harry Potter fans. Sitting actually to the right of platform 11, you can queue up to get a photo taken with the disappearing luggage trolley.
Thankfully, there’s no charge to take your own photo, but I question if the queue is really worth it.
Out of office hours the luggage trolley sculpture is removed, but I’ve seen drunk lad bright sparks improvising with a regular trolley, which looks more crap, but does avoid the queues. Magic.
If you want to stay in London in a backpacker’s hostel that has a Hogwarts Feel, you could do worse than staying in the Rest Up Hostel.
