My husband and I are going to Kauai for our 30th anniversary in a couple of weeks. We are staying in the north-Princeville and want to do a Na Pali coast boat trip. My husband does not get motion sick. I have been on several small boats and never gotten sick but have gotten sick on a big cruise ship (go figure). I love the idea of getting on a boat 15, rather than 70 minutes away from where we are staying and also the idea of being able to go into the caves on the smaller boats but would hate to be sick. No matter which type of boat we take I will take Dramamine. Any thoughts?
