We have been in the non-balconied cabins on deck 6 and loved them. Very centrally located. However, since a balcony is usually a must, we prefer the Cat E cabins on dek 6. Anywhere from 621 (back from anchor) to 631 is great with 627 being our favorite. It is a three person cabin so if you book it, you know there will be no parents with a kid in a cabin near you.
