I've just spoke to someone who's cleared everything up. No one should be getting a taxi because all pickups are scheduled around everyone arriving.
We will be taken to our hotels and then picked back up in the morning for Yarnfield.
I had a similar call this morning. He advised that as I'm staying in Stoke but arriving in Stafford, I should try to continue to Stoke on the train. If not there is transport from Stoke and Stafford to get you to where you need to go.
