Congratulations Peter! I know how you feel. A sharp-eyed friend noticed a reduction in prices on our Golden Princess cruise to Hawaii in October and alerted me. Our Catagory AD mini suite was reduced $500 pp.; so with the resulting decrease in taxes and insurance my total saving was $1080.00.
And all it took was a 5 minute phone call. Now the fare is back up higher than what I originally paid. It pays to watch those prices!!
