My husband and I will be in Amsterdam in mid August. As of now will probably purchase the IAmsterdam card, or perhaps the Museumkaart. I see that for the Van Gogh museum, tickets must be booked in advance. In order to use a card, you need to enter a number from it. Since the card(s) won't actually be in our hands until arrival and pick up of the card, how are museums able to be booked in advance? I'd hate to get there, pick up cards, just to be turned away because I couldn't book in advance .
Would appreciate any advice - thanks in advance!
