avoid this place and save money & pickpockets
I have been a few times here over the past years and believe me it became very bad. Only a few tourists and money robbers. After you pass the cash desk, you will see guys seating just after... actually they are observing you to see where you put your change back ;) in order to take your money later in a cabin or in the dark room. Two guys had money steeled when I was there. I spoke with someone later and the robbers are usually two and they do it well. If you really wanna go, put your money IN YOUR SHOES and no credit cards of course.
