I have decided to use the "Busabout" network to get around when I’m in Europe. ( I have a 5 day train pass too) I am a bit confused about how the system works. I have a youth Flexipass, so I know I can hop on and hop off whenever…I just need more details about how this thing works. Has anyone gone with Busabout before? Did you enjoy it? I will be travelling in France, Spain, Italy, and Greece. Thanks
