Whether it is a beach destination or the countryside, short stays are meant to condense the destination into pill-sized form and be digested.
They are not necessarily aimed at regenerating, but they usually do not entail the stressful sightseeing of visiting cities and are not week or month-long stays in a country aimed at absorbing every possible aspect of the travel destination.
These are somehow the very definition of tourism: go to a single hotel, spend a couple of days taking in what the destination has to offer, and leave.
