You don't need 100% fool-proof internal movement tracking since it's just intended to reduce the volume of tourists in a particular area. I would think just limiting the number of tourist visas a particular destination airport can accept would be fine. Sure, you can drive from an airport in Tampa to go to Disney World, but it would massively reduce the number of people. (That being said, Disney is probably a bad example since it's not built on a world heritage site you need to limit foot traffic to, it replaced a bunch of orange groves in the middle of nowhere)
