Hi Yoko. We are happy to learn that you enjoyed the ride. There are different types of tours in the park, ranging from 20 minutes to one hour. The drivers working for cash misinform online customers to convince them to go with them only to find out that they would charge them much more than what they say at the beginning. The $100 price is for a short ride, 20-25 minutes. Our ride is 45 minutes and it follows the long circle in the park. Prices are generally higher during Christmas period and the cash payers end up paying more for a tour that is much shorter because the driver would not have any responsibility for providing a good experience., they would just try to finish the tour as quick as they can.
