I want to book a very last minute Europe trip for a few days. My current plan is to travel to Brussels on Eurostar. From there I would do day trips to Cologne and Amsterdam. Am I right in thinking that I can get affordable trains from Brussels? Is there a rail card available?
I was thinking of actually basing myself in Cologne or Amsterdam, but Eurostar apparantly won't let me book an inclusive ticket there, and I think Brussels is more central for both.
And my final (naive) question is; having gone through passport control en route to Brussels, do I have freedom to travel through all European countries?
