I booked a campground site, not realizing that Florida State parks uses ReserveAmerica for payment instead of simply charging customers directly. A month later I was charged $90 for a membership to a junky discount website called Active Advantage. They automatically had my card information, though I never registered any information with this website. I had to call the bank and get a new card so they cannot "renew" my membership or charge me further surprise fees. Tricking people into signing up for useless memberships when they are booking family activities? Wow. I would expect so much more from Florida Parks.
