We didn't have a great experience with a Goodwill guide. She met us at Osaka port and took us to Kyoto for the day. We didn't understand a word she said. Her English was terrible. She was very nice, so we didn't want to hurt her feelings and leave her. She was free but, we paid for her round trip bullet train ticket from her home to the Osaka port, the bullet train round trip Osaka-Kyoto, all local transportation, admissions, lunch plus I brought a gift from home. It was a few years ago so I don't remember what it cost, but she wasn't worth much. She wasn't very knowledgeable and didn't take us to many sights. Just our experience.
