Please note that the ticket is only valid on the day you have chosen to book. Whilst we will try to accommodate the exact booking time this is not always possible due to variances in the schedule based on local factors and you may be asked to take a later trip on the same day, excluding Sunset trips. If for any reason you cannot travel a full refund will be provided. Advance bookings do not give you priority over other passengers who pay on arrival. Thank you and enjoy your trip.
