I'm helping out a friend who is looking to go to Alaska in July. They have 2 kids (7 and 5 yrs old) and a couple of grandparents tagging along. This is their FIRST cruise.

I showed them Norwegian Jewel, Disney Wonder and Ruby Princess. Here are the 3 side by side: http://cruiseline.com/cruise/compare/38519-2015-07-18/38533-2015-07-20/42717-2015-07-19

What would you all suggest? I was thinking Disney, but they are a bit concerned about price. Any other options for July Alaska cruise with family?
