Budapest Metro

When we visited Budapest, w bough the three-day public transport pass which included the Budapest Metro, buses, and trams. I think it was worth it because that way I didn't have to go buying tickets one by one or even passing them through the machine...you just had to flash your pass at the subway guard and that was that. Also, the price was more than fair. Plus, Budapest's public transportation system is very intuitive. For example, we were at the Hungarian Parliament and wanted to go to the piers where the boats leave the cruise the Danube. We looked at the map and saw that the tram ran along

I was told by one of its employees (who scans tickets in front of the entrance of subway) that a single ticket is a one way ticket, which can be used to travel in one direction. I bought a ticket and ride for one stop and went out to take some pictures. When I re-enter the subway, there are people stood there, they scanned my ticket and let me in. when I went out the station at the next stop, another guy scanned my ticket and told me I used an invalid ticket and charged by 30 euro ... I was wondering if the ticket doesn't work, why did they let you in the first place.

Takes you almost everywhere in the city, never waited more than 3 minutes. Wow!
