Julie, very difficult to compare one line to another for pricing, given the different things included (air and excursions in particular). Forgive me if you already know this, but if you opt to do your own air, you will receive a credit on Regent if you don't. Usually $800-$1,000 for destinations to Europe or further. Have you found that Silversea and Seabourn don't do the same?

I know what you mean about sticker shock. You just have to figure what perks you enjoy and will use on the different lines, and go from there.
