In the lightning thief Percy Annabeth and Grover had to go all the way to LA to get into the Underworld, yet in the Last Olympian Nico and Percy only had to go to Central Park, in NEW YORK, wich is relatively closer to LONG ISLAND NEW YORK! WHY DIDNT THEY USE THE DOORS OF ORPHIUS WHEN THEY WERE TWELVE? It would have saved them like..... 99% of the time they had to find the lightning biolt, Ares could have acosted them in the park and given them the back pack then but JEEZ what the Hadez?
