I think the camp system and the fast travel teleport system are still bigger offenders in making the BG3 world feel like a theme park.
In my first playthrough, I jumped in the hole in the phase spider lair. Found myself in the Underdark and it was exciting and amazing. UNTIL... I clicked on the map and realized I can just freely teleport to any fast travel spot on the surface. The party had no idea where they were or how to get out. That was a massive, massive immersion killer for me. Larian make it possible to stumble on such a location, then pull the rug from under their own adventure completely.
I agree, fast travel must be restricted
