OK, so went ahead and walked through the booking for Alaska on the Discovery, August 7. Looked at the cost, then logged in and the numbers went down, but not 25%, about 23%. I contacted via chat Princess and they said that the discount was applied to my account so I am seeing the final price, not sure why their 25% is slightly different than my 25%, but we are talking about $30 between both of us. I put it on hold for a day, just to chew on it for a few minutes. the actual cruise before port fees and insurance was $1008 per person.
Honestly, $2500 for a balcony cabin and Princess Plus (also port fees, which are crazy in Alaska and insurance) to Alaska is a really good deal. Since we live 40 minutes from the dock, there is no air, no transfers, no hotels, just the cruise cost. OK, Princess's roll out of this promotion was bad and communication almost non existent. I hope they work on this and also consider that making this offer to teachers in May is OK, but making it in January for the year would be fantastic.
Pretty good deal and I will survive the clunky customer service
