Yes, “Big Ben” is what they call the Elizabeth Tower stairclimb. Tickets for April have not been released yet, but I have the release date marked on my calendar. However, whenever I have gone to the official site to “practice”, it is not “live”—-that is, no matter what supposedly available date I click on, it will not advance to the next page. Nor can I change the calendar forward or back.
This is on my iPad using Safari. Maybe I should just try on my husband’s Mac? I have not had this issue with other booking sites.
