A big disappointment !!
First if you must go, buy the City Pass, it will you save you a 2 + hr wait in line to buy tickets, and when say this I'm not kidding! Second, the City Pass will get you into all the attractions like the 4D show. the water show ect. Without the City Pass you will be stuck to just the aquariums, or you will have to purchase everything seperate which is quite costly. The place is way overcrowded with people, the water show lasts maybe 20 min. tops and the whales and dolphins do not do very many tricks. the 4D shows are geared more for young children, so if you have teens i would skip this attraction. Save your time and money for something else in Chicago, or save it, and visit Sea World.
