1.5 months of preparation, 12 tennis teams, 15 versions of the O2 Arena and O2 Universum plan, 17 days in the O2 Arena almost non-stop, over 50 rooms for the organisers and tennis teams and strict coronavirus measures. We’re not going to lie, this was probably the most challenging two months of the year for much of our team. Preparing the Billie Jean King Cup International Tennis Tournament in record time seemed almost unrealistic at times. But we did it. In addition to getting it built, played, won and demolished, it looked nice. And there was even a pre-match light show.
