Why is a Disney Cruise Better than a Carnival Cruise?

cruise-ship-floating_MkYuq8__Asking for a friend (not really, I’m asking for myself).  

If a Disney Cruise sounds like an awesome idea but you can’t afford it, what would be a great alternative?  I can’t see paying what they are asking for at this time for my family of four.  I’m thinking about either just taking the fam to the actual Disney World or taking a Carnival/Royal Caribbean cruise this summer.  We don’t go on family vacations every year so I want to make it semi-special this year.  Of course if you are a representative from Disney, Carnival, or Royal Caribbean I would be more than happy to blog and Instagram about my experience.  What is a good family oriented cruise line?  Leave your comments below.
