This place is great! I am a nanny and took the 4 year old boy I care for here. It is a wonderful place to take your well-behaved little ones. They give you a headset for no additional charge so you can have the full experience. As you walk from country to country your headset will follow as well by playing music from that country. This really helped to keep the kids attention. They also have an interactive room where the kids can play with all sorts of different instruments from all over the country.
My one complaint is that the ladies at the front desk as well as two different volunteers were extremely rude about bring children into the museum (we had a group of about 5 kids and 4 adults). On the website it was pretty clear that they are kid friendly. Yet they were obviously not excited to have the munchkins there to visit. But who cares! Still take your little ones because this is something wonderful for them to experience.
