I paid to the man in the street for a tour in Spanish. I speak English, but my mom doesn't. He told me that there was not a problem with that. I took the bus from Hollywood and nobody said nothing about the use of earphones, the different chanels, etc. When I could to listen something in my language (for 10 minutes only) , we arrived to the point to change to the blue route. That second bus had not available the language system. When I asked to the guide (from Chicago) what to do he said "unfortunately the language system is not available in this bus" and he went to the second floor. He didn't care at all. My mom looking through the window bored and annoyed for more than 1 hour of ride. Me trying to translate something! It was a very bad experience. We saw the most important places in LA but we know nothing about them! Don't say there is language system if this is not working. I felt you have stolen my money, 100 usd, nothing cheap!
