Hi Madalene!
It's so exciting to be planning a Disney cruise! Depending on the ship you choose, you have a couple of options for staterooms.
On all of the ships, a Deluxe Family Stateroom with Verandah could accommodate your family without having to use an upper bunk for your little ones. These staterooms are designed for families of five and have a wall pull-down bed in addition to the upper pull-down bed and convertible sofa. On the
Disney Magic and Disney Wonder, these staterooms are category 4A, 4B, & 4E. On the
Disney Dream and Disney Fantasy, these staterooms are category 4A, 4B, 4C, & 4D.
A different way to do it, which is sometimes less expensive, would be to book two connecting inside staterooms for your family. We have done this with our children, and having the extra space is such a luxury.
I hope you have a wonderful cruise! If you have other questions arise, please feel free to ask them here.
Happy Cruising, Tracy V.
