I had my 11 year old son with me. We did the museum and the aquarium in about three and a half hours but that wasn't even getting to look at everything. He was so excited he just couldn't wait to see what was around the next Corner what was around the next corner. We are going back next weekend and taking our time but you could literally turn the aquarium in the museum into an all-day trip. Decently priced food, drinks, and activities.
We went in at about 1:00 and came out vat about 3:30
I say 2.5 hours for just the aquarium and another 1.5 for the nature museum. So many details.
Plan on a few hours at least! So many things to see! I dont think you can even see everything in one trip.
