We ended up getting different tickets once we arrived because they were so much cheaper at the site. These were a great place holder in the event they didn't have anymore tickets
My only issue was no signposting at the beginning so had no idea which line to join but once through security it was straight up the tower. We enjoyed the exercise of the stairs and the viewing platform for photos was great.
We came early and was fantastic. No lines at all and the access was super fast. We managed to reach the second level by stairs and it worth the effort.
Very good. You can skip the line and dont have to wait. Worth to go to 2nd floor. We had a nice time.
Worked so well. It was the only place tickets were available a week or so before our visit for our desired time, and we received the tickets a day in advance without any prompting. It was perfect!
