Does anyone know if you have to complete the journey within 2 hours or just start the final part of your journey within 2 hours? For example, if you touched on at 12:00, then touched on for the return journey at 1:55 and touched off at 2:25, would you get charged a 2 hour or daily fare?
Edit: Tried it. Was charged a 2 hour fare for a journey last touched on before 2 hours and touched off after 2 hours.
You need to complete your journey in the 2 hours so you'd be charged for the daily fare in your example. However if your first touch on is after 6pm then you will only be charged a 2 hour fare as long as you touch off before 3am.
