Ahoy, Kimberly!
Congratulations on considering a Disney Cruise Line vacation for your family's next adventure together! As a family of six, we have experienced just about every possible combination of staterooms you can have -- two staterooms on entirely different decks, staterooms on the same deck but separated and adjoining staterooms. It really depends on the make up of your group.
I can tell you that my preference is adjoining staterooms. It allows for the flexibility of everyone using one room to gather in while the other one is designated the "quiet room." Plus, you have the added benefit of having two sets of bathroom facilities from which to choose at any given time. In addition, you don't have to fret about packing as much since everything is essentially delivered to and stored in the same place.
For your group, it's going to depend on when you desire to sail and the availability of the individual ship. However, I suggest trying to book adjoining
Deluxe Family Oceanview Staterooms with Verandahs. You'll have the maximum amount of space with the greatest flexibility at the most reasonable fare. Plus, your partitions on the verandahs can be removed to enjoy a shared outdoor area.
I hope that helps you plan. Have a wonderful day and a magical vacation. Bon voyage!
