We were there towards the end of the schedule so it was not that packed. It is overall nice, but really overpriced for what it provides.
The visit takes about 1 hr (stopping for pictures and reading some of the info about maribe life and different seas and oceans). If you go with kids, expect to spend some 2 hr.

On a separate note: I was disspointed on the bad state of the aquariums' plexiglass (or whatever the material is) - it so scratched and old in some places that it's hard to take a decent picture.
