Oceania fares: Marina class ships cheaper than R ships?

1. It will take too much effort to gather and compare. Taking a cursory look, it appears that the per diem fares, allowing for factors like geographic location, time of year, length of cruise, etc., are lower on the larger Marina class ships than the R ships for the same cabin categories, namely penthouse mini suites and balcony cabins. This is true even though the cabins on the Marina class are a lot larger than on R ships.
