buy your tickets online with time, (i mean days or weeks), before going.
it can get really crowded but that doesnt make the experience less joyful, the place is incredibly cool, very different to anything else i had seen before, it is full of color and mysteries, perfect for kids and adults, i walked around for nearly 4 hours and didnt get to see all the rooms, it has many secret rooms and some keep changing so it is easy to get lost and loose sense of time. the rooms and halls have sounds and sometimes music but i was glad i had my headphones with me.
also, eat before going cause there is no restaurant inside, they have free lockers, and also chains with locks to secure things that dont fit inside the lockers, like suitcases.
after leaving i felt that the price was fair.
