What is Evensong? Is it a Mass or just singing? Is it better than a tour?
I have seen a thread that says that the Ripper tours are not worth it. Is that the concensus ? I saw people say that most of the places are gone and there is high crime in the area.
Also my kids like Harry Potter, but it seems that we are going to Kings Cross station, St Pancreas, and Millinieum bridge and I know about Leathenhall. So does that cover most of the London sites? Also can we purchase an Oyster card at Heathrow? Do we purchase one per person or since we are a family of 4 should we purchase one and all use it? Thank you.
