Some good points above.
However after all of the add ons with the premium lines (port taxes, service charges/tips, specialty restaurants, shore excursions, and last but not least, drink packages) you come pretty close to what a "bottom of the boat" fare is for Regent. Oh, and I almost forgot above, air fare.
So are far as we're concerned, Regent is actually a bargain ....
And as a lazy so and so, it's all done for you.......
