Hi Terri,
This a very subjective opinion, but I wouldn't go in an H cabin even if it was free. The vibration in cabin 667 kept me awake most of the nights. On the other hand, my husband was not bothered by it that much. If you don't mind feeling "magic fingers" under your bed then you don't have anything to worry about. I think the price differential between G and H cabins is usually not that much.
