I really don't think we'll get a POV from either Percy or Annabeth. Since no myth from any reliable source talks about tartarus and just describe it as a big hole with nothing inside, it'd be messing up mythology to even give details about it. For me we'll only see them as they close the doors and Percy or Nico is left to stay there. It'd be a nice closing for the greatest hero of all.
