You have the same mindset as me and the States! Even though I never did the camper/road trip thing (which is my dream!), most of the times I come I try to stay for many days and see more than one city - ok unless it's a nyc city break, done that only 4 days :)
Don't expect much standard photography London posts - I don't even know if I'll take my camera with me (can't stretch enough how I'm NOT a fan of London :P ) but there will be some awesome ones with the girls for sure ;))) Thank yououou!!!
