Creo que es gratis a partir de las 3pm, pero no puedo asegurar que sea todos los sabados.

I just checked in the internet and it says that there is a technical stop from 7 January to 4 March. You can find the exact days according to season. They are different in the summer and winter.

Funny you ask, my friend and I discovered the museum by going up a completely different way then the stairs in front of the fountains. There is a back access that has escalators that take you all the way up to the museum and we went down the stairs when we were leaving. So if you are facing the fountains you take a left and walk down and then a right, something like that. I think there might still be some stairs that you might need to take to get to the escalators but they aren’t as many! Hope that helps :)

Yes, moreover we came around 14:30 and entered for free. Keep in mind that all people somewhy queue at one entrance (in the inner yard) whereas there is absolutely queueless entrance from Ronda de Atocha street ; ) Enjoy!

Да, из самого здания тоже можно подняться вверх по лестнице.Спросите, как пройти у администраторов на месте

We bought a Barcelona card 5 day pass and didn’t have to book a time or day we just walked in and it wasn’t busy. I don’t know about changing a booked time.

No Idea about it. Talk to them. It is difficult to reschedule.
