I spent hours Googling in preparation and found these reports of earlier trips:
Palau: Our Pacific Paradise on BootsnAll.
Brad has a detailed trip report with wonderful pictures. You'll see his detailed trip itinerary also.
Two Rock Islands kayak trip reports by the same author on TravBuddy.
DCRainmaker's three day tour
The Palauan Kayak Misadventure shows you what can go wrong.
The wonderful Kayaking Palau by a woman who also did the adventure by herself and with whom I had the pleasure of corresponding prior to my trip. Thank you Barb! She is the only one who did not use the services of Ron Leidich of Paddling Palau which is affliated with Sam's Tours' Planet Blue Kayaks but instead went a very independent route with Impac.
