try to get one that has both. We booked an inside cabin on Reflection which had both. Our 13 5'5 yo loves pullman beds. He would have been comfortable on either the sofa or the pullman bed, but if given a choice, he always chooses the upper bunk. So, it depends on what your kid will be comfortable in at that height and whether he is still agile enough. 🙂
I am not, but I am 50, not 15. 🙂
Here is a link to our cabin review with pics:

I was surprised by how spacious the inside cabin was. We are so used to microscopic cabins on RCI Oasis class....
