Some of the local Green party activists are pushing for a "transport hub" near Templemeads. After the experience of trying to get a bus home from Templemeads at 9 pm, we opted for a transport hub that works: Bristol Parkway.
It costs 5 pounds a day to park here. Even with fuel costs, that's less than the bus fares for two people. It's way cheaper than the taxi too. And if your train from London comes it at 11pm, you can't be sure there will much of either around. Yes, Bristol has an integrated transport hub today: Parkway!
