I have not sailed in that exact cabin, however, have sailed in the cabin next door (E728) on the Diamond Princess, the sister of the Sapphire. I LOVE that location. There is no traffic in the hallways and we did not have any problem with noise from Club Fusion at all. Some say there is a vibration at the back of the ship, however, we did not experience that either. We have stayed in that last mini-suite on Emerald deck twice and have same cabin booked on the Crown Princess this year. I think you'll enjoy it very much! Have a great first cruise!
