Fixed camps are always going to be immersion breaking if there's considerable distance to cover on a map.
DA:O was particulary bad - I mean it's ridiculus to think that the party is walking halfway across a kingdom to do a quest, then walking all the way back again to the same camp to sleep! They're spending more time travelling than there are hours in the day!
That said, the map isn't so huge in BG3. Except for the underdark, we could have a temporary camp there rather than climb a mile long ladder twice each day!
Eh, in DA:O the camping place wasn't really as recognizable as the one they've chosen for BG3 (no temple, beach or anything like that, just a tiny lake).
The travel was also instantaneous unlike when you moved from place to place, and the camp wasn't even in the traveling map but out of it in the top right corner, so i just imagined they'd set it up wherever.
