My family and I are disneyworld fanatics also but we love Busch gardens williamsburg also. My wife and I also can't tolerate roller coasters much anymore but really enjoyed the ones at BGW. They are all very smooth and fun. My kids were 15, 10, and 9 the last time we went and they loved the rides in the Sesame Street area along with meeting Bert and Ernie, Grover, big bird and the gang. Also they enjoyed the rides in the Italy area. I hate that you missed the train ride as it is long and the scenery is beautiful.
