We are thinking about taking the Dawn Princess/Alaska but are running into the problem we had before - two small children (3 and 5) and Princess does not have any cabins that allow more than two passengers. The mini-suites apparently allow three passengers but that still doesn't help. How have other families gotten around this?
Princess does have quad cabins, but they may be either unavailable or in a higher category. Normally, I would recommend a balcony cabin, but with a 3 yr. old, that may not be safe. What about all the other Princess ships sailing Alaska or better still a Royal Caribbean or Celebrity ship which both have family cabins and a great Kid's program. Get a good TA too. One that will give you options. Most newer ships have cabins which will accommodate 4 with two upper births the kids will love. On this site, put in a "I want a cruise" request and give your details. You will get answers!
We took our 7 year old and he loved the bunk which the steward pulled down from the ceiling each evening. It was above our bed and had a guard rail but if he had managed to lever himself over that, he would have just landed on me in bed anyway! I know another woman who took her 4 and 7 year old with two bunks that came down from the ceiling.
MV Regal Princess, which is operating the "Inside Passage" itinerary during the coming Alaska season, does not appear to offer third and fourth berths. The four ships that will operate the "Voyage of the Glaciers" itinerary -- MV Sun Princess, MV Dawn Princess, MV Sea Princess, and MV Ocean Princess -- all have quite a few cabins that can accommodate third and fourth passengers. On these vessels, all of the outside cabins in categories E (Emerald Deck), FF (Plaza Deck) and GG (Plaza Deck), most of the outside "obstructed view" cabins in category F (Dolphin Deck), and a few outside balcony cabins in categories BB (Aloha Deck) and BC (Baja Deck) will accommodate four passengers.
