I do like Princess more than alot of cruise lines when it comes to stuff like this - they're easier to work with.
Just this week, I had a couple who booked a 10-night Alaskan cruisetour and the price went down tremendously. They made their final payment a month ago, yet Princess repriced it for me and they are being given a $2,008 refund!
Most cruise lines would not have done this.
46 Cruises & Counting! Favorites: Paul Gauguin to Tahiti: Uniworld River Cruises in Europe; any of the Celebrity Solstice-class ships; Holland America for 12-nights in the Baltics & Russia; RCCL for 14-night Greek Isles, Turkey, & Croatia; Holland America for 14-day Alaska cruisetour; 10-night Canada/New England cruise; 21 days in Hawaii including a 7-night NCL cruise; Oceania for 25 days in Asia; & 3 months touring Europe by train. And many days spent in all-inclusive resorts!
