Hi Lucy, and happy birthday to Mr Ferguson. Casual hire costs from £2 per day at the terminals, if you’re a big group you should probably aim to start at one of the bigger docks. Once everyone has paid their access fee, all you need to do is print out a release code at each terminal for an onward journey. There is no group hire facility in the scheme as it operates on a first come first served basis, but as long as the group isn’t too big you should be okay. Have a good ride.
