Thanks for all your comments. I have to agree with Ka Honu's ratings (except we haven't tried Seabourn) as well as his comments about Regent pricing. Frankly, I am surprised that except for sea days , breakfast & lunch are primarily buffet style.
We've also cruised on larger ships & found Celebrity suited us best. Itinerary is most important to us followed by cruise line quality, ship size, service, food, etc.
