I pre-purchased my Van Gogh Museum tickets online 2 months before my visit for the last time slot of the day because I had Anne Frank tickets for 12 noon the same day. If I didn't pre-purchase, I would have missed seeing the Van Gogh Museum because everyone walking up to purchase tickets during my time slot were turned away because the museum was at capacity and tickets were sold out for the day. It taught me to always pre-purchase online whenever the venue offers this option. Never leave it to chance. I am so thankful I was able to see this museum.
