Hershey Park or Sesame Street for 3.5 and 9 yr old?

Trying to decide on a weekend trip with a one night stay in PA. Deciding between Hershey Park or Sesame Place. There will be 3 adults, and 2 kids, ages 3.5 and 9 years old. Trying to figure out if there would be sufficient entertainment for both kids at one of these locations. I feel like Sesame Place maybe too young for the 9 year old, but Hershey may be too old for the 3.5?? I have never been to either, so hard to decide. What was your experience?

We've been to both and absolutely hate Sesame Place and absolutely love Hershey. Granted it's been at least 5 years since Sesame, but both times (went once on Saturday and gave it a second chance during the week) it was overcrowded and simply dirty. Hershey never feels overcrowded, it's not dirty and it's a more wholesome family place. We've been going to Hershey since my kids were 3 and 4 (now 8 and 10)and there was plenty for them to do.
