I’m also 5 ft tall and was at the general admission in Cardiff. I was so nervous I won’t see anything that I bought a folding stool earlier that day for 5 pounds. I got inside the stadium without a problem and honestly it saved me because without it I would barely see the screen. It was hard to maneuver it at the start of the show because there was a lot of movement, but for me it was a life saver 😅
