Super crowded, at least on weekends. The actual path through the aquarium is pretty short, but the gigantic aquarium near the end is amazing! There's a cool shark aquarium too. If you buy your ticket online, you can bypass the long queue for tickets. You'll need to get onto Sentosa island. The train takes ezlink cards as is only S$4. It's at the first stop.
