Pre booking the vouchers on Klook gave us ease of skipping the massive ques for ticketing purchase. We came on a Saturday, probs not the best move as regardless huge crowds going up. But an amazing experience as we got to see the sunset over Tokyo. The glass floor was a let down as minimal glass experience compared to Melbourne's Eureka Skydeck, none the less a beautiful views of a wonderful country. Don't forget to get your free groupie picture at Tembo Galleria Level (or purchase a larger version for around 1200¥) as soon as you exit the elevator!
