Ah, very tough decision

Let me see if I can help:
Ask yourself what you see your dream honeymoon being
Is it you and hubby lounging by a pool all day sipping cocktails and then maybe taking lots of "naps" together or even massages in the hut or laying on the hammocks together
If you answered yes, pick Tensing Pen

Do you see yourself having fun getting out and about around Negril, going to the pub crawl, traveling down to the beach or maybe even taking in some Live music at Alfreds or Seastar? Maybe even a day trip?
If you answered yes, then pick Banana Shout



However, also consider this.....you know you will come back again, so don't feel you have to do everything in one trip. This is your honeymoon, you only get one of those (well, if you're lucky)
