But we have seen in the first chapter of The House of Hades that the group has been running into problems. Ourae have been preventing the ship from getting to Greece for a few days. Leo also mentions having to replace the mast a few times, so they have obviously run into problems. I mean they have to rescue Percy and Annabeth before they can stop Gaea.

Also an interesting note, August 1st (the day Gaea is supposed to rise), was the day the original Octavian added Alexandria into the Roman empire. Our Octavian may want to do the same thing, bringing Camp Half-Blood under his control.
