Considering the Stanley House Hotel London in London?

Platform 9 3/4 by joits
On my way to Edinburgh, Scotland via Kings Cross I made a point to go and find the 9 3/4 platform so famously portrayed in the Harry Potter movies and books. I wasn't really expecting a whole platform, it turned out to just be a wall with a sign of the numbers 9 3/4, but as a Harry Potter fan, I still thought it was pretty cool.
