Hello 5008 and welcome to cruise chat;
As long as you don't mind a little walking, there are no problems associated with being all the way aft. On Coral Princess and sister Island Princess just about everything is from midship forward.
If you crave peace and quiet you are in the right spot. The pool and open deck area one deck up from you is the most underutilized part of the ship--always quiet and plenty of deck chairs available.
