Yes, each park First Aid center has stock epipens on hand. It's actually listed on some of the maps now. Thanks to a new law in Florida places like theme parks sports stadiums, and restaurants are allowed to carry stock epi. It's definitely recommended that you bring your own as you'll want to have it on hand. The stock epi is supposed to be a backup if you need more before the EMTs arrive or in cases of first time anaphylaxis events when someone doesn't even have epi yet.
