Separate locations with movements between them on the global map would definitely be better suited to the dnd game, and would also will be no need in silly fast travel points if the transition to another location is always somewhere nearby.
I mean, I don't think the silly travel point would be needed anyway. At least not in the convoluted magic waypoint way. Either set "safe zones" where you can freely travel from and to (perhaps could be also used for long rest) or just replace the system with the Witcher (and many other games) fast travel system - signposts and implied mundane travel. Mechanically similar or the same, but much better in terms of immersion and worldbuilding.
