Guest Reservation

Q I would like to cancel my guest booking.

A
You can cancel your reservation online or by email.
You can cancel through the login page until the applicable cancellation deadline. The deadline varies depending on the bus service, so please check your [Reservation Confirmation] email. Once the deadline has passed, the cancellation button will no longer be displayed.

After the online cancellation deadline, please contact us by email or contact the emergency contact listed for pre-departure inquiries.
Please note that the emergency contact may have specific business hours. If so, cancellations cannot be accepted outside those hours.
