It's not for me. Himself has to have an angiogram and will probably have to stay till 9pm (missing last train to Hereford) so he needs a hotel room for the night.
The Cotteridge area of Birmingham is just a short bus ride from the QE and has a lot of B&Bs along the Middleton Hall/Bunbury Road. They are located near to King's Norton railway station.
I would personally go for the town option, the university train station and the 99 bus stop are close to the hospital and there is more choice of good hotels in the city centre.
the travel lodge at rubery will require a bus trip from the QE
