We may try dry ice this time. Gary's right; you can get ice just about everywhere - except if you're at anchor in the middle of nowhere. We found that we needed to replenish ice every other day. We have no refrigeration.
What you get/bring will depend on the size of your boat and your tolerance for roughing it. For instance, I could care less about onboard showers or air conditioning. My answer for both is to jump in the water.
Here's more stuff to bring culled from last year's survey:
"Quick-loading water guns. Swim ladder."
"Sailing dinghy. 25 gallon bucket for water fights!"
"We bought: Screening material, tarp for cockpit shade."
"A little clip-on electric fan helped with the heat. We forgot a lot of stuff: next year, a packing list! Also next year: Boogie boards, a sailing dinghy, a dodger for the bash back."
"Biggest purchase was a kayak from West Marine."
"I upgraded my battery monitoring system, we brought a hard sailing dinghy and 2-inflatable kayaks (but only found time to launch one). We followed hard-earned lessons from last year: drink LOTS of water (we always had a jug of package-mixed Gator Aid in the refrigerator), eat regularly even if you're not hungry, remembering to take a cool shower aboard and having an easily-accessible swim ladder for cool-down swims, and keeping ice in the refrigerator."
"I bought a $125 air conditioner. I purchased the unlimited delta drag out for $34 and used it to save $600-800 off Tinsley Isl. Net the openings for next year. Used all the toys especially the water guns. Sun shade is a must."
