Hi, I've got a question about 100 minute ticket, particularly about its validation. My journey will start with metro and then I'll take a bus. I thought I'd have to validate the ticket only once, when entering the metro station. But the website says:
"Make sure you validate your ticket at the beginning of your journey and when you switch to a Metro line (if you change vehicle within the 100 minute time limit, the ticket has to be validated again to be usable until the end of the journey)".
Do I need to validate my ticket the second time (when entering the bus)?
