Holland Pass or Museumkaart?

I think the better choice is to buy your tickets at the venues you wish to visit.

It depends on the museums you want to visit. The Musumkaart is good value if you are visiting at least 3 of its museums.

The great advantage of the Museumkaart is that it is good for places all over the Netherlands, for a whole year. When I bought it in April 2012, it cost about €45, and I used lots more than that in value (I was in the country for 10 days, and used the card in Amsterdam, Rotterdam, Utrecht, Delft, Leiden, and the Hague). As always, you have to do the math to see if a pass is worthwhile.

Thank you for your replies. We will be in the Netherlands for six days, so looks like the Musemkaart is our best option.
