Our tour was multi lingual, 40 people half English speaking, the other half Italian. First part, Philadelphia was nice. Freedom bell and the old historical sites, as well as the art museum's stairs (Rocky stairs).
The Amish tour was a shame. The guide have not bothered to fill the carts with same language groups, so we were packed with 12 loud Italians, with no possibility at all to hear the Amish guide explanations. The tour guide did not take the ride. At least he could join the Italians and it would have been better also for them. We expressed our disappointment to the guide, who did not bother to react. At the end of the tour the guide demanded a gratuity to him, the driver and Chinese and Japanese guides who joined the tour. Be aware!
