It depends on the age of your son. If he is young, the sesame street play area is a blast. We loved the cirque de soleil type show. I thought the Shamu show was overrated. It tried to be so "special" that is seemed a little boring to me. The other shows were great. We loved some of the rides too. Some of them were geared more for older kids. There are opportunities to get wet, so I would wear clothes that dry quickly. Also, be careful of the sea gulls. They will steal food off your plate. My whole family loved Sea World when we went, and the ages ranged from 2 to 9.
