Honestly, I have no clue.
See, every year, my former math teacher, math idiot extraordinaire (and I hope to GOD that he doesn't read this) takes about 40 kids to... where else but London. In my opinion, his obsession with this city is beyond disgust or pity - it piques curiosity. It's that bad. His room is cluttered with London stuff that I'd never even DREAM about going near to, let alone buy.
...
He stays with kids in Royal National Hotel, which is apparently in Bloomsbury, which is just about ten minutes from one of my campuses at Strand (who would have guessed that Kings College London had over 5 campuses... not me). Incidentally, the only time I was in Bloomsbury was when I accidentally took the wrong turn from Covent Garden back from school (well, I was trying to get to Picadilly, oops) and ended up right by Gower Street. Therefore, have I ever seen the hotel? Nope?
But coming to think about it, I think Finnell's little group knows more about London than I do. Sure, I can tell you if Boots or Superdrug has cheaper soap, or where you can buy the cheapest carrots (which is not Borough Market, but Tescos at Monument... who would have guessed). I can tell you how many Prets I pass by when I get to Strand Campus, or what's in the London Bridge station, but beyond my home ground, I'm clueless. I have no idea how to get to Tower Bridge, although I can explain to you about 4 different ways to get to Stamford Street in Waterloo (well... I can see it if I walk about three minutes from my residence... would that help?). If you ask me which way to Harrods, I'll probably end up leading you to Leicester Square instead. When it comes to the famous parks (AKA Hyde Park), I can't even locate them on the map. As for Stonehenge? Well, anything outside of London is a mystery for me - there's Scotland up in the north, Wales down somewhere in the southwest (and even that's dubious), Ireland is to the west. The other places are... well, they don't exist on the map for me. So there we are.
So all in all, London isn't a fun place, folks. Especially when you are dodging gruntled businessmen to get to the class on time.
Oh, and the best sandwich around: Tescos.
