Here's how you do it. Buy a Coleman (or likewise) cooler for $15, pack a travel bag in the cooler as well as a blender, a knife and a hand juice squeezer. Fill the cooler with the rest of your stuff, clothing, etc... Take a roll of Duct Tape and tape the cooler closed and use it as your checked luggage. Keep the duct tape in you hand luggage if anywhere along the way they want to check it open you can tape it closed. Once in Negril you've got a huge icebox, blender, juicer, a clothes bag for your return trip home and all your stuff. Fresh OJ for breakfast, Cold Red Stripe when you need and a blender for mixed drinks. You give the blender and cooler to someone worthy when you leave and you have accomplished all your goals.
