So context
I will be traveling up from Switzerland to Bonn on Friday then from Bonn to the track on the same day. I have seen and looked up travel times and routs. I wanted to ask

Will Bus 860 survive the high demand of visitors?

How to pay the Bus 860 ticket fair as an international traveler?

What would be a good time to leave Sunday ?

Will public transport even be a viable option?

~ I am potentially looking a rental car from Bonn if anyone has suggestions
