EDcruising

I have never been on a cruise before but going with people that have, They have stayed before in Deluxe Mid cabin but we are now looking at the Aft cabins and i am looking to book 11.743 too for the Norwegian Fjord cruise. My apologies as was trying to see the responses to elieilleile but cannot see them, Any help greatly appreciated and also has anyone had first hand experience of the white canopy spoiling their view? Huge thanks
