You don't see as much though, and your options are more limited still. And the options you do have are likely more touristy as a result.
As always, the most easy to reach places will have the most people. I would say that's not what you're going for in such a trip.
All true. Also: Weekend holidays involving flights are a completely unsustainable and irresponsible form of tourism given the climate crisis. Not that anyone much cares.
