Sure, Madame Tussauds wax museum is overpriced and cheesy, but its focus on local culture makes it fun: 'meet' the Dutch royals, politicians, painters and pop stars, along with global celebs (George Clooney, Barack Obama et al). Kids love it. Buying tickets online will save you a few euros and get you into the fast-track queue. Prepurchasing tickets online for earlier than 11.30am and after 6pm nets further discounts.
