Having climbed virtually every inch of Fun Holiday over the years taking pictures and setting up wifi, the only rooms with a balcony with a sea front view are the top floor rooms in the opposite building from what has been circled (I took that pic). Both these rooms overlook the pool and this is the view from one of those balconies.
Since there are only two rooms on that end of the building, your privacy would be as private as possible. Enjoying an early morning coffee or night cap in a nightie would be perfectly acceptable and as we all pretty much know, about anything goes in Negril. You could be enjoying a 7am Red Stripe in your underwear and I seriously doubt anyone would notice, let alone complain.
As Lisa started the saying years ago, "what happens in Negril never really happened..." (grin)
