Most of our time is spent (on our family visits) in Amsterdam. LOVE IT! My kids all 20 somethings LOVE it there. Generally safe and very easy to navigate around. I would also recommend you see the country, as it is also lovely, and totally different than the cities......then there is Markham, Vollendam and some lovely little villages we also totally enjoy. We find the people delightful. MUCH different than France. I did not like PAris at all. I thought the people were rude. However-Provance-breathtaking, but you DO need to speak some french or be able to fake it really well. We usually travel to visit a friend who has a villa there, so he takes us around and does the French speaking for us-only issue is-we have to eat what he orders. Lol
You will find that Amsterdam has a wonderful ethnic mix and fabulous food of all types to go with it. ALso familiarize yourself with the laws-smoke ONLY in the Coffee shops. You will smell it on the street, as well as be offered if (they are not pushy), but ONLY the shops.
