Question: Is there a place to store valuables while in the water? I'd like to bring a good camera for the rest of the tour but obviously don't want the camera right near the water with me. Have thought about bringing a dry bag with me but I'd prefer not to carry it with me if I don't have to.
A suggestion for taking pictures while doing a String Ray City tour, just buy a disposible water camera at home and use that for that day. No worries about bringing a good camera and you'll need a water camera for in the water too. You'll just leave your stuff on the boat anyway, so just bring enough cash for small purchases, tips, etc. and your sign and sail card.
Your valuables will be totally safe on the boat in your beach bag, wrap your good camera up in a towel and stash it in your beach bag. The tours are very safe, they have to be, their livelyhood depends upon it.
