Here are my answers to all three of your points :D.

1. Just because there are no texts about what Tartarus is like, doesn't mean he can't describe it. That's where imagination comes from ;D. And besides, there IS text (people have described Tartarus as a bottomless hole of darkness, fire, acid, and other fun stuff). And he doesn't have to make a large chunk of Tartarus POV, just maybe a little (like Percy and Annabeth reunite with the others, and their POV is like a flashback).

2. Reyna and Nico actually have a good chance at getting their own POV, even if it's short. Once again, the flashback theory could go really well with Nico, while we learn Reyna's true thoughts about the Greeks, the Romans, and the Prophecy altogether. Still, they might not get one. It's a 50/50, 40/60 kind of thing.

3. If I were a bestselling author, yes I would do that. Because it creates drama, atmosphere, and gets the reader emotionally connected to the story.

As a side note, I always thought that Riordan might write a book detailing Nico's travels after The Battle of the Labryinth and The Last Olympian. Like, how did he find the Roman Camp? Why did Peresphone turn him into a danelion? And if he knew about the Romans, does he know about the Egyptians too? You could create a entire miniseries centered around Nico. He's one of thse characters that you know everything about, but not everything about.
