I'm taking the plunge and heading off to Europe in the fall for 3 months. It's my first time travelling there for an extended period with no real plan (1-way ticket to Europe + trains + leave within 90 days).

I've looked around Google and other forums and can't seem to find a (recent) non-conflicting statement regarding:

1. Do I need have to a return flight booked? If I'm not returning from the country I land in, does customs want to see my final flight out of Europe, or are they looking for my flight/train out of the specific country? Does anyone have recommendations for a good place to start where this is usually a non-issue?

2. Proof of funds - had anyone had to show proof of funds before? If so, what's the best way to do this?

I'm sure these are basic questions, but I searched the forum and had trouble finding something on this topic.

Thanks,
Chad
