Arriving in the morning, it was already quite crowded. When I asked the attendant if I wanted to exchange my entry ticket (scan the barcode), I was directed to the regular ticket counter. After queuing there, I scanned the barcode in another line, and then moved on. The place is quite nice, with four pool types: adult, lazy river, small pool, and small indoor pool. The queue for food and drinks is quite long. It's recommended to visit here only on weekdays, as weekends get really crowded later in the day.
