Seamless entry, only by showing the barcode of the digital ticket. There were lots to see and enjoy. The place was big enough to push a stroller around. Our 1.5 year old daughter was so excited to see the sharks! The shark tunnel was definitely the star! We didn't manage to see the penguin feeding, but we did for the sharks feeding and it was cool. The biggest minus point for us is the price, because the tourist price is so much higher than the local price (which is very understandable, but still we think there are lots of places more worth going to with the same price tag). Also, the picture booth is so overpriced with low quality, unfortunately.
