Having arranged for a shark encounter for Tigana, Mary cast around for an equivalent experience for Kasia. (Four year olds were not allowed on shark encounter, and she wouldn't have been able to snorkel anyway.) Thus, the dolphin encounter at Sea Life Park, an hour bus ride from Waikiki. I wasn't sure how Kasia would react, but she positively glowed for the whole time. It was pretty cool! And we learned that dolphins shed their skin seven times a day, to keep their skin hydrated and free from parasites etc. Consequently, their skins are incredibly soft -- "like butter", Mary says.
