I was at the Rodent last May. I can substantiate GF's statement. If it's on your person deeply concealed you will be fine. I carried in my Smart Carry then transferred it with my spare magazines to my Safepacker in a restroom stall. All they do is poke around in your bags with a stick or at least that was the last time I was there. This is standard for all Florida amusement parks. A note about Six Flags, Six Flags (which there are none in Florida), they do have metal detectors.
I have heard of people being made being asked to store it with park security or being ejected from the park. Depends on the mood of who made you. In either case, you will have your legal CCW status verified by a local LEO and they will check your firearm(s) to see if they are stolen. Typically it's an Orange County Sheriff deputy for Orlando area parks. They have at least one unit assigned to the park. Same goes for the other Florida parks I have been to. Either PD or county sheriff has a unit or two assigned to the park.
The Rodent does not have as many lockers as Universal or Busch Gardens. For thrill rides make sure your carry mode is secure. They do allow you to take your personal belongings on those types of rides at Rodentworld. A Smartcarry or Safepacker on your belt (should you transfer it to that after getting into the park) should work.
If you go to Busch Gardens, Seaworld or Universal make sure your mode of concealment is secure and deep. If you carry in a Safepacker, be as discreet as possible transferring it to a locker. It's possible to remove a Safepacker from your belt without exposing your firearm. I do it all the time. It's one of the reasons I purchased it.
Know the law; don't ask, don't tell.
