We just returned from our first Disney Cruise (3 night Bahamas) and loved every second of it. We live in Seattle so it would be SO easy for us to leave from Vancouver and skip the plane rides and airfare. My question is, how do you think they compare? Will it be cold on the ship in summer in Alaska, or in other words, warm enough to swim and enjoy the deck? How about the ports? Are there good things for a 5 and 9 year old to see and do without expensive excursions? I guess I am thinking that the things we adored about the Bahamas cruise (warm weather, Pirate Party, Castaway Cay most of all!), will be absent and I am worried to pay a huge amount of $ on a 7 night Alaska and wish we were on the 3 day Bahamas again. Thoughts?
