I went on Sunday afternoon, the crowd was dominated by families with kids. There's a free tour guide by schedule if you're interested, it takes around 1 hour. The place is huge, you should wear your comfy shoes. There is only 1 canteen in the basement, they're selling snacks and drinks with affordable prices. You should try ImersifA. You can buy the ticket online (there's a quota for every session). Each session is for 30 minutes, but the show only takes around 15 minutes, somehow they give you time to take photos. I had a fun experience there and also lots of good pictures :)
