I don't know if they still do it but I thoroughly enjoyed my tour of the Hieniken brewery .
Also we took a day trip to some seaside town & also to Gouda---both were fun. The best day trip by far was out to Keukenhof Gardens-they are spectacular.
Don't forget to have some yummy french fries served in a big paper cone with mayonaise to dip.
Amsterdam is a beautiful city but we got lost about a thousand times. The names of the streets are going to make you want to buy a vowel. Good luck & Bon Voyage!!
