Our family paid for the general admission plus photos with the Dolphins which is an additional $25 per person. Our Total cost was $30 per adult and $20 per child. All in all it came to just under $200 for the family. We anticipated a bit more than "a free for all" .
I would not recommend you bringing your "Kids" here, maybe one Kid but not many small kids (we have 3) as you will likely have to fight for viewing space, fight for "spots in line" and just overall battle the other general admission guests for the ability to enjoy a quality interaction or photo opportunity.
Don't waste your money on the "photo with the Dolphins" for the extra $25, as my photo displayed most didn't have wristbands but ended up in better viewing positions than we did as we are not "fighters" , you can easily game the same experience as a paid experience by "fighting" your way to where you want to be.
The entire staff comprises of 20-25 year old females who quite frankly have no idea how to order and create order of a mob. So in turn , hence free for all, it turns chaotic. At one point two dudes decided to have a little "chat" about viewing position and space.
NOT FAMILY FRIENDLY. BE PREPARED TO PAY ABOUT $200 bucks and fight for your glimpse of some Dolphins and animals.
