OK, I just added all the POI that @Chewwy94 listed here.
But there are a few that their names are too ambiguous for me to know the proper location.
- Paradise Inn
- Totem Pole
- Tunnel View
- Jefferson Fort (Is this Fort Jefferson (near Key West) already in World Update 2?)
- Shiprock (Another duplicate from World Update 2?)
If anyone knows, let me know.
