Buying tickets online through the app to avoid the crowds at the gate was a great decision. Changing tickets online was also very quick; the staff advised me on the combo ticket I bought and I even got a complimentary juice from Suoi Tien Farm. The cleanliness of the amusement park was excellent; there was no litter, and the cleaning staff cleaned quickly and always kept the play and resting areas clean and beautiful. Regarding the games, I think the combo package (exploration + Suoi Tien Beach) we went on was just right for my family. There was a snow castle, but it was freezing cold; my hands were numb after only 2 minutes inside. They didn't provide complete gear, only boots and thin cloaks. If you're going, you should bring your own wool hat, gloves, face mask, and warm jacket.
