Disability card


New member
Hello, I have a spanish disability card (I can walk, though, but I have other issues).
I read that you can enter for free with one more person and even skip lines in many museums, but I am not sure. I wrote to the ones I want to visit but some did not answer. I would also like to know if it is necessary to make a reservation. For example in the dome... taking into account the disability could I just go there, show the card and get in?
Can anyone shed some light on this? I am thinking of buying Firenze Card anyway, but it would be a pity to buy it if I am entitled to enter for free.
Thanks in advance.
