Luggage and bags:
Spirit Air has changed their baggage policy. One checked bag per person or pay $10 for each additional bag. Packing our fishing rods cost us $10 each way. Since we brought tackle with us and it had to be checked there was little room for clothes. Fortunately shorts and T-shirts don't take up much room.
Clothing/Shoes/Weather Gear: The weather in the Keys is usually very mild but out on the boat it was a little colder and we were lucky that we brought some warmer clothes. Sandles were our choice of footware but shoes came in handy out at the clubs and nicer restaurants.
Toiletries and Medical Supplies: The Key's have plenty of stores for your toiletries. The airlines only allow 3 ounces of liqued per container so its not a bad idea to buy some down there. 3 ounces of Sunblock is not enough for the intense sun in the Keys.
Photo Equipment: Photo oportunities are around every mangrove in the Keys. Bring a UV filter if you have one. There is water everywhere a good UV filter can be the difference between a good shot and a great one. I just started shooting video recently and I was glad I had my video camera down there! I'll be posting some fishing videos on You Tube shortly! Wavesandfish is my You Tube name.
Camping/Beach/Outdoor Gear: If you are going to be camping or staying outside at dusk you will probably need some bug spray, especially in remote areas. There are some very nice campgrounds right on the water. Don't forget the Sunblock!
SUNBLOCK, (48SPF) SHOULD DO IT!
You will STILL tan! Thr sun is not very forgiving in the Keys so you must protect your skin from sunburn. Even with SPF48 you will still get burned, just not as bad. Also bring lots of bottled water, if you freeze the water in a bottle the ice will take some time to melt and you'll have ice water to cool you down!
