You should probable assume that there is a gator in every body of water in Florida.
I’ve seen them in the retention ponds on the grounds of MCO and even once on the taxiway.
I also saw this one near a the Home 2 Suites hotel just north of the airport off of 436 while I was out for a run.
It was about a six footer.
On our recent Disney trip, we rented a pontoon boat to tour the Seven Seas Lagoon and Bay Lake and didn’t see one. I was looking too because I love alligators… from a far.
