Hello. The general admission to the acquarium is $7.50 but you can spend upwards to $18pp with all the other items on site plus $8 parking, however I purchased the CityPASS... which is $59 per adult which allows you to go to 5 out of 7 Houston area attractions. Basically you have to go to the Space Center, the aquarium and The Museum of Natural Science if you purchase the City Pass. The other 4 attractions are interchangeable which you get to pick 2 out of those 4. I did the math and it's worth over $100 to go to the 5 attractions but the CityPASS at $59 is a bargain. Best wishes.
The Aquarium’s general admission is $12.99 for adults. The general admission includes the main exhibit and stingray reef without fish food. A better option is to get the all day pass which is $20.99 for adults, and gives you unlimited access to every exhibit and ride until the day is closing. Btw, the all day pass does not include the stingray food but you can purchase it for $3.24 and include 4 silver side menos.
