We're not into museums or 'quiet' places. I think we may get away with going to watch Stomp (or possibly Mummamia if i give him enough sugar to cooperate) but mainly it would have to be non-tour non-museum tourist attractions.

Anyone gone to London and done something cool that isnt your typical "this is the London Eye. its see-through. Now give me money to share one of these capsuls with strangers so you can go up high and look at the city from an angle that google earth totally beats".
