I want to clarify how buying the Prado Museum tickets work. If I buy my tickets online in advance, do I still need to exchange for the real paper ticket at the counter? If I need to line up to exchange does the line move fast. I saw some Youtube vlog saying the line for buying the ticket move faster than the exchange voucher line. Are there a lot of entrance where one can line up to exchange the voucher?
I going with an elder and read that they need to validate the senior ticket at the counter. If paying full price will speed up the access to museum I will just pay full price. But does buying online need to line up at the counter as well?
