Itinerary suggestions?

I know the charter company makes a suggested itinerary or two, and there's probably a few other sites with suggested destinations too.

Although they do feature some great spots, they can be busy because they are on the itinerary suggested. I was wondering if anyone knows of any "spots" that might not be on the regular tourist route. Or have spots they particularly want to head to? Little more flexibility but still having a plan to maximize on the experience.

I do know that the recommend stop of either back to the mainland or Hamilton island will be a high priority for both refueling and supplying.
