I am so excited!!! The only thing I love close to anything disney is DOLPHINS!!! So to get to do this with my kids is so exciting!!

My DH and I did it in Mexico years ago!! I have been waiting until my youngest was old enough to not freak out about it to do it at Discovery Cove since it is sooo expensive!!!
ANY advice about it? Things to do or not do? I have heard it is amazing.
Also we get a free pass to either Sea World or Aquatica, which we may be able to swing for a day, which would you guys choose??? We have never done Sea World in Orlando just San Diego. And obviously we have never done Aquatica, but it sounds cool!!! What do you think?
