If we only do one paid tour on our upcoming trip to Kauai this August, it has to be a Na Pali coast tour. We are just having a hard time picking the right company. I've read reviews, but I'm still not sure. I was hoping some of you might be able to help us make the final decision. On Maui we love Trilogy, and would like a similar type of experience. I'm prone to sea sickness so I'm thinking a larger boat would be better. Right now I'm leaning toward the Southern Star. Any suggestions?
