Be careful in Birmingham station .... it is big and confusing. You will almost certainly need to leave the platform of arrival and go up the stairs (escalator if you are lucky) towards the main concourse and change to another platform, of which there are many!! There is always lots of railway employees around and they are usually very helpful. If you miss your connection it will not be a problem because trains to Wolverhampton from Birmingham are frequent.
You could get a tram from Birmingham to Wolverhampton (with a stop at Bilston) but the terminus is at Birmingham Snow Hill station which is NOT the mainline station.

If you choose to travel through by train to Wolverhampton you can pick up a taxi right outside the station and the fare to Bilston is about £7 (12 dollars).
There is new hotel accommodation behind a pub in Bilston (a two minute walk from the venue) called the Olde White Rose (good beer and food too). Telephone number is (01144)1902 498339.
