That's awesome! Glad it worked out for you!!
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.
