I have a business meeting in Rotterdam on Tuesday and I've arranged to fly out on Saturday (arriving at Rotterdam airport mid-morning) so that I can see some of the country while I'm there.
I've been to Rotterdam before, and Amsterdam (but not for years) and a lovely little place called Delft.
Where else can I go, and what should I see? If I can't think of anywhere else I'll go to Amsterdam, but there must be other places - places that maybe I wouldn't otherwise make a special trip just to see.
I will be using public transport, and wherever I end up at the end of each day needs to be somewhere where I will be able to find a cheap-ish hotel easily. I need to be back in Rotterdam late afternoon on Monday.
I like stuff like castles, historic towns, countryside/woodland walks, but also happy to sit and soak up the atmosphere in some little town square.
(Also, if you live in NL, what's the weather forecast for this weekend?)
Thanks in advance for any suggestions!
