I've lived in Florida all my life and can assure you, insects happen here. I don't care how much you spray, seal, etc., they will happen from time to time. That said, I've never had a roach encounter at a Florida Marriott property, but I'm sure it happens. Even the
Happiest Place on Earth (Disney) deals with them constantly as the 1,300 separate threads show. Trust me, Disney's insect control program is absolutely top-notch, but even with that it's still a problem.
