My wife, son and I just got back from sailing on the Harmony 2 days ago...and we were right down from where you will be...our room was 7072, mid-ship on the port side. We were very pleased with the location and the view...the window was high enough above the deck to not be a problem unless you were naked right up against the window. The view was only very slightly obstructed by the lifeboat at top left. The only negative was that we did have to close the curtains to sleep because of the fluorescent lights outside the window lighting up the deck, but heck, with the late night and ealry morning Alaska sun that we had, we needed them closed for darkness anyways!
