KKDay's shuttle service was excellent. Because of rain that evening, our itinerary changed, and we were worried about missing the bus. We inquired about changing the time, and they responded promptly, which was great. They even allowed us to change the time, which we greatly appreciated. However, other aspects of KKDay's service were terrible. For example, we never received our JR train tickets, and customer service didn't respond. My family called KKDay's customer service from Taiwan at 7 AM the next morning, and they only said the voucher had been sent, but we hadn't received it in the app or via email (including spam). This severely disrupted our plans for the day. Because of this experience, we will never use KKDay again. However, this shuttle service experience was excellent, and I highly recommend it!
