After London Bridge, we hit the tube again & rode it to Kings Cross Station. Sound familiar? Do we have any Harry Potter fans out there? In Harry Potter, the kids get to the magical train that takes them to Hogwarts by running between platforms 9 & 10 at Kings Cross Station. It's called Platform 9 3/4. At King's Cross Station, right next to Platform 9 they made a tribute to Harry Potter by making a Platform 9 3/4. I knew we HAD to get a picture taken here. How often do the "Potter's" get to go to the land of Harry "Potter?"
