It's a great way to spend a Sunday. We booked tickets online so could skip all queues and just go straight into the aquarium. The ticketing queue didn't look long though. We visited just before lunch time so the crowds weren't that bad. Things seemed to pick up during and just after lunch with a visible increase in people going through the different viewing stations. There were lots of small kids, so if you prefer a less kiddy afternoon, go during the week when it's not a school holiday.
There's a wonderful variety of sea life from different regions and the creatures look healthy and well cared for. There is a wide variety of eateries and cafes just outside the aquarium. Perfect if you want to enjoy lunch before or after your visit. Make sure your taxi drops you at the correct point. We used the casino entrance. The walk to the aquarium was short from there.
