I echo Olivia's sentiments about the pricing and per diems. Have really enjoyed the product but the per diem in the Med is over 700/night on the Navigator for 2009. Hard to plan much at those rates. Wow!!
One idea for a perk might be for Regent to offer 1-2 cruises per year heavily discounted for the most loyal repeaters (Silver and above). These could be some of the Caribbean shoulder season sailings, etc. or one late Med. So it would be like a SSS discount...only better.
