On the high end, you can charter TimAir from the Negril Aerodrome to the Ken Jones Aerodrome in Portland. You will get a great view of the entire North coast of Jamaica - it is really the most beautiful island. You will need a driver in Port Antonio. Check out Reach Falls, lunch at CliffHangers maybe dinner at Soldier Camp or very cool GeeJam's restaurant then back to Negril. The Boston Jerk center is cool to see but I way prefer the barrels of Negril.
