We're planning a trip to Williamsburg for next month. Any tips for doing Busch Gardens with a 3 year old? She's a thrill seeker, so she will love any ride she can get on - is there a lot there for her to do? Also, has anyone done the "Dine With Elmo" lunch/dinner? Is it worth it? Or are Sesame Street characters fairly easy to get pictures with outside of that meal? Thanks!
