Congratulations ! I think you will love GP Jamaica for your honeymoon the sunsets are amazing.
So, things that I think may interest you as a new couple would be..
1) A couples massage
2) A sunset dinner at the Poseidon a la carte restaurant.
3) Some time at the adult only beach and Coral Pool.
The Palladium Hotel Group website also mentions this “Honeymoon couples can also enjoy other amenities such as a superior room upgrade (when available), a fruit basket, a bottle of rum and a romantic a la carte dinner.”
I am sure you will find plenty to do and will discover your favorite place to hang out. Dont miss trying the Jerk Chicken from the hut located at Sunset Cove, served every day at lunch.
