We stayed in the royal family suite on the mariner and had a huge aft balcony. We splurged alot and it was worth every penny. The best views leaving ports in from the back of the ship and even though it was alot of walking to the back it has been the best balcony and views we have ever had. Would definately recommend trying an aft room at least once. We only felt the vibration from the engines when pulling into port.
