In an older edition of Rick's London book he says that if you buy your ticket for the London Bus tours after 14:00, it is also valid the whole next day. Both the original bus tour and big bus tour state their tickets are valid for 24 hours. Does the after 14:00 purchase still apply? Rick does not mention it in his 2007 London book.
Also, Rick says the walking tours are "silly," but big bus tours has a "Beatles Walk," my 16 year old muscian son would enjoy this, if it is good. Does anyone have any information as to the quality of this walk?
Then the big question--Original or Big Bus? Rick says both are good, what do you say?
Thanks in advance.
