The Whitaker Science Center was a nice Museum to visit if you happen to be in downtown Harrisburg. The Museum is located next to or within the Hilton Harrisburg. The museum has some nice attractions and is just the right amount of "science" for the kids. I have an 11 year old and an 8 year old and both enjoy going to the center each time we are in Harrisburg. The 3 levels that it occupies has something for everyone. If you happen to be there when they are presenting, it's great since the groups are usually small groups and intimate; you can ask a lot of questions and get the attention from the staff while they are presenting.
After you finish up the visit, there is a Starbucks next door so that you can get your caffeine fix. Another must do is have lunch or dinner at Momo's BBQ across the street from the Whitaker center. It has great BBQ and a HUGE beer list for those who enjoy the out of the ordinary beers. It's also kid friendly. I would recommend the fries since they sprinkle them with the same rub they use for their ribs.
