It is a nice aquarium although not huge. The theater experience at the end is pretty cool where it rotates between 4 exhibits while you sit in an auditorium thing. We sprang for the optional helmet dive experience and it was neat, but probably not worth the high price. Very expensive for this excursion and the water is freezing cold. Granted you get to go underwater and swim with the fish, rays etc but they charge you a pretty penny for it. The admission to the aquarium is also not cheap so expect to drop some cash on your visit here.
