I grew up in that part of PA, and always loved going to Hershey Park, and we go back usually every couple of summers, because I still have famiy there. We went back this last summer and took my ds-7 at the time and dd- 2 and 3 months. Honestly, it was kinda a bummer, because my 2 year wasn't able to go on a good amount of rides, and a good number of the ones that she could go on, adults couldn't go with her, so she didn't want to go anyways (even with my ds going with her.) I think part of it is that I'm really used to WDW now, and this was the first park, other than WDW/DL that we took her to, so I'm sure I'm just used to more. If it were me, with only have a 2 and 3 year old, I'd probably wait a year. Another option is they have another park (not in Hershey, but in Lancaster, very close) called Dutch Wonderland, which is designed for young kids. We used to go there a lot when I was younger too, and it was a lot of fun, so you may want to consider that. You could always get on both of their websites to see exactly what they both have ect. I will say the first time we took my ds to Hershey Park, he was 3 1/2 and was able to ride a good amount more than what my dd was able to do last year. Hershey really is a great park, and IMO, so much better than any kind of Six Flags or the like that I've been to, and I think will be great to take my dd to in the next year or so.
