Hi Annika. Thanks for your recommendation. The tour is advertised as two hours guided plus one hour self guided pre-booked entry to Christ church. So it sounds like your guide didn't manage the tour duration well. I have pointed this out to him that many folks are on a busy schedule. I agree that it is an expensive tour but it's also an expensive tour to run. The entry fees alone cost £21, if you were to have paid directly. That said, the same £21 actually means I have to collect 20% extra to cover VAT liability then another 25% to pay viator commission. So I actually need to charge you £35 on here just to then be left with £21 to pay the entry fees alone. We do offer a more economical shorter version of the Harry Potter tour which only goes to the Divinity school and it costs £40 instead of £75. As for your last comment, yes, this tour is not entirely about Harry Potter - it also introduces Oxford university and it compares student life here with insights throughout into the making of Harry Potter. I don't see how anyone could run a tour in Oxford that was purely 100% only Harry Potter as it wouldn't be an Oxford tour...which is how we do describe the tour. Anyway, thanks for choosing our tour. Sincerely, Alasdair
