Wondering what the top rated excursions are in Waikiki? We want to take surfing lessons and also do a snorkling excursion. We are staying at the Hilton Hawaii village in Waikiki. Family of 5 (2 adults, 3 boys ages 16,14,11) We arrive Dec 27 for 1 week. What are the "must do's" in the area? Best place for snorkling??
