Tahiti Question

From my research, Princess Cruise line has a cruise that leaves out of Tahiti and makes various stops -
It is a 10 day cruise and the cost various depending on room. I know for a balcony suite
that cost is about $5000 for two people. Now add on airfare to tahiti and you are looking at $7000 total. Which is good considering you get all your meals.
I know it is possible to get it cheaper if you reserve a room without a balcony.
hth!
