Wes - we would love to do a South American cruise - unfortunately we still have one daughter at home (the other one leaves for college this weekend). In a few years (3-we are counting)we will be looking at this itinerary. I would love to hear your thoughts when you return. Have a great cruise - I do not think that you will be disappointed with Oceania. The other item that I did not mention is tipping - as it is automatically added on your account and to bar bills we didn't see any difference from Regent other than the charges on our bill at the end of the cruise. As you mentioned the fare difference more than makes up for a bottle of wine at dinner and tips.
