Hi LeeAnne,
Yes, the cat H cabins are only on deck six. The vibration is felt( by those who feel it) in the cabins at the back of the ship, not only on Cat. H cabins. But there are many people that are not like me and either don't feel the vibration or it doesn't bother them.
Have you asked your TA if your cabin assignment has been made? You're already past the final payment date so I would have thought the cabin assignment should have been made by now.
