@Docwagon , if its December then @phil bottle is spot on so maybe finding a nice place where the England fans will be would be truly an experience! Also, you must go to the Harry Potter Studios which isn't far from London at all. An unbelievable day out and nowhere else quite like it. Maybe watch some films and then come to see it for the full effect and experience?
Imo though, you should come around Noember 11th, specifically Wales. You know, so you can be with all the FGers meeting up for our biggest ever meet. 😎 But yeah, if you can't, I think @Plumbers Crack 's thought of catching is definitely worth mentioning when you've nailed down dates. 👍
