Once we got into London, Caroline went to a meeting while myself, and the three girls headed to Trafalgar Square first. It was rather busy but we spent 20 minutes or so wandering around the square, looking at the street art and climbing on the lions. Since I had been in that area a two months earlier, I remembered roughly where everything was and how to get to our final destination: Ripley's Believe It or Not in Piccadilly Circus.
While it may be expensive, it's not a bad value as Ripley's is not wanting for activities or exhibitions to see. We spent almost 5 hours there and didn't read all the exhibits! There was also a really cool "Mirror Maze" (that we all got lost in) and a Mission Impossible-style laser room (which I failed at, due primarily to my size).
