Here's the website :
http://www.seaworld.com/seaworld/fla/default.aspx
If you purchase 7 days in advance (online), you get $55.95/adult and $43.95 for you dd.
At the gate, you'll pay $61.95/$49.95 (online without 7 day advance purchase).
Not sure what time of the year you're going, but they open at 9 am every day and close anywhere from 6 pm to 11 pm depending on the time of year. You can check the website for that.
If your dd is non animal loving, not sure how much she will enjoy. I can't imagine her not enjoying the whales/dolphin shows though ? There are a couple rides there (Journey to Atlantis, Kraken, Wild Artic). Kraken is a high thrill steel roller coaster---don't think she's old enough for that.
I believe SW can be done in a day, especially if your dd bores of animals. My kids love the ocean/sea life, so we can easily spend 2 days there.
Maybe you and your dd could plan a nice lunch together. They have a restaurant there where you can view the huge aquarium underwater as you dine called Shark Grill or something similar.
PS---also, I know SW used to accept
AAA discounts for some dining/admission/merchandise.
Hope this helps.
