Ahoy, Kim!
I have a 15 year old wild sleeper, too! She is definitely NOT one to share a bed with!
I am happy to report that the
Deluxe Family Oceanview Staterooms with Verandah onboard Disney Cruise Line that sleep five people have four beds. There is a queen bed for the adults to share. Then, the couch folds open into a twin bed. There is another twin bed that "magically" appears out of the ceiling at bed time...your kids might all fight to sleep in this one! The last bed is a murphy bed that folds out straight in front of the verandah door.
With all of the beds down and ready for sleeping, walking around your stateroom will be a challenge. But, at least everyone will have their own sleep space.
When you are onboard, be sure to book your next cruise! You will get to take advantage of a 10% savings on most future sailings, plus you will receive an onboard credit on your next cruise. You might consider booking two connecting staterooms for your family for that sailing as well, it gives you more space plus an additional bathroom. This is invaluable for our family with a tween and a teen! Also, by doing this, it gives you a separate room for naps.
I hope this helps with your cruise planning! Please visit us here at the Disney Parks Moms Panel with any other cruise questions that might arise before you set sail.
Happy Cruising, Tracy V.
