£9 for the shuttle bus from Park Lane etc!

Thats only £4 more than a return on the 2 or 78, The shuttle coaches will not be full of doris and bettys moaning about how busy the bus is and how disgraceful it is that they cant get to sit in their usual seat, also they are running direct from end to end and then no waiting around for ages in a huge queue at penshaw ornament for a service bus to see if they can get on to go home.
A bargain if you ask me, an uber would cost double that each way on the weekend

Agreed. Most likely lots of roads will be closed etc so im assuming normal buses (non shuttles) will be diverted. They usually put special provisions on for such large events
