Penny - I think the "G" midship cabins (which you and your friends have booked) are the best of the standard cabins for location. We've stayed there twice - once in 641 and once in 648. We've also sailed in 877, a stern cabin on the same cruise with Dolebludger. We felt some vibration in 877 on that particular cruise, although not to the same degree that Richard and Carol found. We haven't found either of our midship cabins on deck six to have a vibration problem. Hope that helps! Cheers, Anne
