As there are often questions posted here about the London Pass and is it "worth it", I thought I'd report my experience to help others decide.
I bought the 6-day LP online for 89 pounds when they were offering a discount promotion. I used it all 6 days and saw Westminster Abbey, St. Paul's Cathedral, Windsor Castle, Churchill War Rooms, Queen's Mews' and Queen's Gallery. If I had paid individually, the admission costs would have been 85.50 pounds.
However, the fact that we didn't have to wait on any ticket lines was priceless to me. When I'm on vacation, "time is money."
I'm sure I would have used the Pass for 1 or 2 more attractions except that my husband insisted we spend so much time shopping. (LOL)
So, in deciding if the London Pass is a good deal or not, consider all the factors.
