Two adults traveling with a 6 year old. Just about every museum we plan on going to is free for her. We figured it would makes sense to get an I Amsterdam card for us, but it's 4 euros for all day passes on the GBV for her and she's free to go in just about everywhere. However, using the card to get timed tickets (Van Gogh museum for example) requires entry of the card numbers for each ticket. Do I really need to get a third discount card for her when she's free?
Any thoughts on this?
