Transportation between Spain, Netherlands, etc?

Noordwijk

We woke up to rain and thunder so a lot of us here decided to stay in Noord for today.. the weather is gorgeous now though. I'll go back to Amsterdam tomorrow for perhaps one more day, then head maybe to Brussels on Wednesday or the Hague.. or maybe Rotterdam. Any recommendations are welcomed btw.

I just saw that you're already back in Anchorage. So how did the trip go?

What cities/countries did you visit and which were your favorites?
