It's so long since I cycled that I probably don't remember how (and I would most likely end up in the canals) ... but we did park up the car at the hotel and travel around on the tram. Doing things "the way the locals do" is a sureway to get the flavour of the place. I once flew from Fort Lauderdale to Gatwick with a convention of travel agents who were coming for 2 days to see "London and Stratford" by coach; I asked "but isn't that too short a time" and felt very sorry for them when they said "no - that's what our customers come to see so it's all we want to do".
Back on topic - there was just too much to see and too little time - our day was a "bonus break" on the end of teaching a Java course. We took in the Madurodam model village, the seaside resort of Scheveningen, the office area of Rijswijk and Delft. With more time I would have suggested Keukenhof (the dutch tulip garden), Amsterdam and more - and also looking around the Hague a bit more - for example, the Mauritzhaus (err - what is that? Can you tell us more?)
Oh - and the biggest giggle? Eating a Mexican meal in a restaurant run by an Egyptian in a Dutch city. Since we're British / American and have never been to Mexico we don't know if this was the real thing, but somehow I hadn't imagined that a Chimichanga should be covered in Edam sauce and sprinkled with crisp-fried onion shavings.
