My Wife and 17 year old daughter traveled on the Grand Princess inside passage from 8/3 to 8/10 RT from Seattle. Alaska was the Star Here, Grand not so much.
We had the owners suite with a balcony off the back.B751 Room was dirty and dated. The Deck was big and awesome.
All the inside passage ports were great. In Ketchikan we did the Misty fjords with Captain Randy of Mountain Express. Great excursion and you can do it privately without the ship, save some money and he even takes you to land. Town was pretty cool.
