I went one year, and the following year I went with family, and my 5 year old nephew went, too. I took him on the Jaws ride, and sat him on the left side of the boat, and in the lagoon I looked over the edge at the water and was all curious, and about the time he started looking, Jaws popped up out of the water and he popped up out of his chair and was making a bee-line across me and several other folks.
That was great.
Since they took away the GOOD Ghostbusters show at Universal Studios Florida, I'm not that interested in them anymore.
