On our very first trip my youngest was 18 months old. He loved SeaWorld, and his favorite?? The ducks swimming in some of the streams. Yes, we traveled 1100 miles and he wanted to watch the ducks, which were just like the ducks at his gramma's condo in our home town!! Fortunately my parents were also with us, and they took the bigger kids to go see all the exotic exhibits and DS and I spend a lot of time in the shade watching the ducks. Hey, he was happy!
