+1 to OP. Another very unimmersive feature of the game.
I think they best solution might be a few camp locations scattered across that map that you actually have to discover and travel back to in order to use.
As others have said, most content in camps is the normal conversation cutscenes, which wouldn't need any extra work.
Not sure how they would manage the bounds of your camp if they were in specific locations around the map, though...
I hate the idea that once we arrive in Baldur's Gate, when we hit the Long Rest button we will just teleport to an Inn and not actually have to move through the city to find an Inn to rest.
The Fast Travel system needs reworking too. I'd much rather we had to be within range of a rune to actually fast travel. Much more immersive.
