Beside the clothing, pack some of those Purex 3in1 laundry sheets. They don't weigh much and will be great, saving money on detergent at the laundry facilities at the resorts....and pack some dryer sheets as well even though the Purex supposedly has fabric softener in them.That Florida water is wicked! I always plan on doing laundry while I'm relaxing poolside. I only take about 4 days of clothing to save room in my luggage Pack plenty of barrettes, hair bands and sun visors as the heat will make that hair stick to your face. Ponchos, phone and camera chargers, camera manual in case you get a camera acting up, you can fix it. I always take a packet of those pre-moistened wipes, like baby wipes, to swipe away the sweat and keep my hands clean. Also some purell or germx stuff. Of course, your travel documents, confirmation numbers, etc. I always take a picture of those items, as well as a picture of my ticket, front and back, or room key, so if I lose them, I'll have it ready to produce digitally. Of course, if you lose your camera, someone else may have access to it. I have also photo copied my credit card so if you lose it, you'll have the information to call right away...safe in your room safe. I'd pack a couple pair of shoes and maybe switch off every couple of days. Dry wicking socks in the summer may be important...I've also heard of people using spray antiperspirant on their feet so they don't get blisters although I could only find spray deodorant. (Can you even travel with aerosol cans any more?) Back packs...I like to wear a small backpack around as well.
