Luv the aft balcony---lv the door open on warm nights and hear the water from the wake --or to sit and watch the wake.
We have an aft balcony for our anxiously anticipated Panama Canal Cruise in November. Unlike desrtcruzer we are lower doen because we found the noise froom the Lido Deck all night and early am cleanup to be just a little distracting.
I haven't been thru the Canal since 1973. I was on a small vessel--120ft and it was a great transit. Thought my wife should see one of the Wonders of the Modern World, so I campaigned against her choice of Bermuda and was successful.
