Well worth going spent a week there a few years back and i'm returning for a long weekend this summer. The night life is great but it can be expensive as it's a major city, this said if you have your wits about you, you can find some good deals.
The RLD is a hub of activity even if you aren't after paying for sex, bars, coffee shops, smart shops etc and as said it's a real experience. As it happens out hotel was right on the edge of the RLD.
There's plenty to do over and above what a lot of people think, it's a stunning city that unsurprisingly has a real laid back atmosphere. There are some weird and wonderful (or not so depending on taste) things going on and it could be a real eye opener.
MY one bit of advice is personally, avoid the Anne frank house unless it really interests you... the que to get in was huge and i found the whole thing a little dull. Maybe that makes me an uncultured moron but it's just how i felt.
If it's a nice hot day rent your self a pedal boat, grab a 4 pack of beers and if you smoke a little bit of weed and have a very pleasant ride around the canals. Great fun!
Enjoy!
