I have been at the shark reef aquarium two times, the first time was with my mom and brothers and we loved it and the second time I brought my kids and they were super happy, the aquarium is small but it's so worth it, my kids were going crazy with the sharks and the stingrays at the end we went to the polar exhibit, I got to admit I was not impressed with the "ride" the looong wait was definitely not worth it.
Again the aquarium is small so take your time walking through it or else you will finish in less than 30 min.
