I was thinking about the same question. DS is anaphylactic to peanuts, nuts, and melons. I'd like to take him to Seaworld, Aquatica, and Discovery Cove. Ultimately I think we have to talk directly with Sea World. I've just sent them an email about food allergies and their restaurants. I will post any response.

Dietary Needs
The Culinary Operations Team at Discovery Cove recognizes the importance of all aspects of food safety especially those challenges our guests with food allergies encounter when dining out. On the day of your visit, you are welcome to visit the Laguna Grill early in the day to discuss their personal needs with one of our chefs. Our Culinary Team, like everyone else at Discovery Cove would like to provide you with piece of mind that your day will be as enjoyable, and safe, as possible.
Discovery Cove does provide Kosher meals. In order to ensure they are prepared to order, we ask guests to visit Laguna Grill 45 minutes prior to their anticipated lunch time.
Discovery Cove does provide Vegetarian options for our guests.
I can't find any specific dietary needs information on the Aquatica website, so I have emailed them.
