We're considering another trip to Madrid next March and one thing we did not do our last trip was buy one of these passes. I am thinking we should get them this time since we did travel the metro alot.
I'm wondering how it works. Is it the same kind of ticket you get for a one trip ride and put it in the ticket taker slot? Or is it something bigger in which case, how does one enter the metro?
Hoping someone out there knows. thanks much!!
