London photo: crowded Platform 9 3/4
If you want to get your picture taken at Platform 9 3/4 at King’s Cross Station, you will have to wait a long time. Also: this is nowhere near the actual platforms 9 and 10, which I think ruins the illusion. These fans don’t seem to care, though.
The Harry Potter photo spot used to be between the actual platforms 9 and 10. Then major reconstruction and renovation work at King’s Cross displaced it. Now it’s just a tourist trap. (There’s a Harry Potter shop next to the new photo spot, which also requires you to wait on a long line to get into.)
