No Florida resident discounts, but getting the Fun pass makes it possible to get in free for the rest of the year basically. The price is the same as 1-day admission.
We opted for the 2-year Gold pass for Busch Gardens/Seaworld and basically have been going for free for over a year.
There usually is an offer at the beginning of summer on Pepsi cans that gives $5 off admission and sometimes coupons at Wendy's or places like that that give a discount to the park. If you purchase your tickets on line you can get a discount too.
