Book in advance
Booking ahead of time might save you time and money, especially if you visit Amsterdam during high season (between June and August). During the summer, hostels in the city center are frequently fully booked, and some attractions can have long lines if you don't reserve ahead of time.
If you intend to visit the Anne Frank House, make sure to purchase a ticket online before going. Keep in mind that each day only a limited quantity of tickets are available. Prepare to wait hours in a line that usually wraps around the block if you don't buy online.
When it comes to major museums, the Amsterdam City Card is the best alternative. Most of the city's cultural attractions, including the Van Gogh Museum and the Rijksmuseum, are free to enter. It also comes with unrestricted public transportation use for the duration of your card. This is one of the top Things about The Netherlands You Should Know.
