Absolutely worth visitReviewed by: Scott, 2015/06/11
Voucher redemption was easy & quick. We received the tickets and also headsets with ipod type of multimedia guide, which was very informative. The dome is absolutely beautiful, it's definitely worth visit if you are spending some time in London.
You must climb up the stairs to get to the whispering gallery and upper floors. It is actually exhausting to get up there, but the breathtaking view of London is awaiting for you. Highly recommended.
