Two of Kapolei's best-known attractions on one ticket: Coral Crater's three-line zipline course, then admission to Wet 'n' Wild Hawaii with its 25-plus slides, pools and attractions.
It is the easiest full-day recommendation for families staying in Waikiki or Ko Olina, since both sit on the same leeward stretch.
