If you're expecting stadium-size crowds but want an indoor arena, then be sure to consider the Crystal Hall. Built to host the 2012 Eurovision Song Contest, the multi-purpose sports and concert arena can hold up to 27,000 spectators. Its name comes from the diamond-faceted exterior, inlaid with arrays of dynamic LED lights for an extra special light show in the evenings. The corridor around the arena's perimeter is divided into two, with 15 entrances on each side, two transportation access points and several booths to supply food and refreshments.
