I was just in Madrid a month ago an did the Bernabeu tour. It looks glorious, and while the tour doesn't take you pitchside or to the changing rooms, they have made up for it by using lots of cool tech in the museum part with all the players on big screens doing their poses. The upper tier is ludicrously steep and there's cool night club like sky boxes above near the roof. There was a concert on the next day so the pitch was retracted away as well. Really huge club and adidas store in there as well. Highly recommend the tour there along with the San Mames one in Bilbao
There's been an epiphany amongst stadium owners in Spain over the last 10 years, that it does actually rain in Spain. Pretty much every stadium in Spain's top tier of football has, is currently building or is planning to shelter fans from the rain, particularly in relation to this video with Getafe.
It wouldn't surprise me for Madrid to be awarded the Olympics for the edition after Brisbane, although it'd probably be South America or Africa's turn first. Maybe Egypt's new administrative capital in 2036 then Madrid in 2040. Seems some way off.
Asking for a friend, because I am American so I obviously know everything, but where do people park their cars in these stadiums? All stadiums seem to be planted in the middle of humanity... Is it all public transportation access and no one drives cars?
