Hi Gail,
Without knowing how tall your son is, it's difficult to know how comfortable he will be in the pull down bed at
Disney's Port Orleans Resort - Riverside. When my son was twelve-years-old he was around 5'2" tall and he fit in Disney's pull down beds but was very close to being too tall. I have seen measurements for the pull down bed that vary between 63 inches and 67 inches long. I think ideally my son would have liked a little bit more room, but the bed was more comfortable than the floor!
I would suggest the Family Suites at
Disney's Art of Animation Resort for the beds and for the extra bathroom. As my kids have gotten older, we have appreciated having a little extra space in our hotel rooms. When we're trying to get ready for bed at night or get ready for a long day in the parks, having two bathrooms is a luxury! When you add in the kitchenette and extra beds, plus the fabulous theming and splashtastic pools, I think Disney's Art of Animation Resort is a great choice!
Please let me know if I can help you with any other questions!
Wishing you a magical vacation,
Amy H
