As for the sea sickness. I have been a violent sufferer all my life. laast year in Hawaii someone gave me this suggestion and it worked. Take a double dosage of whatever you plan to take the night before your excursion. Then take one pill the day of. I tried it and it was amazing. I took a day drip up the coast in Kauai, a snorkling trip, a helicopter trip, a fishing trip, and a sailing trip-and no motion sickness! We had done a catamaran and another helicopter and I was so sick I couldn't see anything and prayed I wouldn't embarras myself. I can get motion sickness swimming too many laps in a pool. So try it and enjoy yourself.
