Is Traveling by Bus Safe?

I've not taken this particular bus, but I've taken numerous buses in Europe and a few in Portugal, and I'd think it would be very safe. Buses in Europe seem very safe in my experience.

We drove that route, similar to a US interstate highway. Vigo is a small city. There was nothing I can think of to fear for a twenty year old man. . It would be a long distance bus service. I think there is also train service.

I greatly prefer trains to buses, but in Portugal I found that the trains (which I took as often as I could) were often woefully inconvenient compared to buses. There is no airport train station in Porto, so he'd have to get to one from the airport. An inexperienced traveler would really be better off getting the bus directly at the airport if possible, I'd say.

Let me just say that the European bus drivers are far superior to the bus drivers in the U.S. And the buses themselves are often very luxurious--including having WIFI. Go for it.

Thanks for all the responses! We are going for it! I think he should be fine and now I feel even better about it.
