The camp site design is really weird and unimmersive but it doesn't look like they want to let it go.
They should have just placed the camp locations on the actual map to begin with, with fast travel access points. It's as simple as that but no, they had to change it to something else.
This is very clearly a case of "if it's not broken, don't fix it". But they fixed it by creating X amount of virtual pocket dimension camp locations that looks like the real world but are completely disconnected from it. There can never be enough of these locations to make sense in the game world, and there will always be the weird disconnect of "where is this place, why is Withers everywhere, why does the camp site look identical in every cave or at the opposite ends of the Underdark, or how can the Duergar not find this huge section?"
I just don't get the point of going through the effort of creating all those great looking camp areas when they add nothing but disconnect to the game. I would like to camp with the Tieflings at the Druid's Grove when in the middle of Goblin infested wilderness like any sensible party would do. That would even create a deeper connection to what's happening over there. But Larian created a "system" for resting and it doesn't have to make sense or be immersive because it's "just a game", right?
Yup.
This is one of these cases where their stubbornness with a weird design decision costed them a lot of additional work and STILL doesn't match far more simple and elegant solutions like having contextual camps already placed on the map (like in Solasta) or setting systemic rules for how and when a player can create a contextual camping site at will (as in Kingmaker or WoTR).
Their solution is far more demanding in terms of human resources while still coming off as vastly more limited, convoluted, disconnected and immersion-breaking.
