I have doors with box triggers that will transfer me to different levels. The only issue I have is that when I come back into my open world level it spawns me at the beginning of the Third Person Example Map is there anyway I can set a spawn point after I open the open world level?
You would need to save that location, and if you unload the level would need to save it externally. So you would with in the BP launch the save signal and send in that location. get started here:
If you never unload the level you would just Teleport your player to that world location, this is if your keeping your locations persistent in one map.
