From the Gleaner article:

" Bartlett admitted it was a concern, but told our news team that his ministry’s marketing campaign had been pushing messages to encourage visitors to adhere to the protocols. Further, he said, the risk was “mitigated by the strict adherence to the stay-in-zone order, so the tourists can only be on property”. "
Clear as mud. This makes it sound like like the stay-in-zone order is actually a stay-on-property order.
