As a confirmed cruise-a-holic who retired rather young to endulge in my favorite pass-time, cruising, I was delighted to see the prices of the cruises you have mentioned. I have taken three cruises this past year, two weeks (round-trip) to Alaska on the Raphsody last July, 10 day canal on the Crown P. last spring, and a quick 7 day on the Zandam. The only real "bargain" was the single rate on the Z. Any tips on getting good single rates for one who like to cruise frequently?
