It's very affordable and super convenient. The waiting spot was very close to the hotel, just one train stop away in the morning. The bus was also very easy to identify. Although the driver wasn't Taiwanese, he was very friendly, skilled, and professional. There was no tour guide on the bus, but many places in Okinawa are very friendly and have a lot of Chinese signage. This tour also included an audio guide, which informed us about the next stop while on the bus. I think it's great, and the guide is available in Chinese, English, Japanese, and Korean. We stopped for about an hour at smaller attractions and three hours at the aquarium, which was just about right and acceptable. Most importantly, it was really convenient! 👍👍👍
