Where in Wolvo are you staying?
As above, black country museum could be worth a trip, RAF Cosford isn’t too far away. Head to the retail park in Wednesfield if you want a few shops and a cinema with some places to eat.
There is the metro which isn’t running from Wolvo city centre at the moment but just down the road and that will take you in to Birmingham and you can then do sealife centre and all sorts.
Forgot the food bit.. There is a pan asian buffet place called Cosmo in Wednesfield by the cinema, a nice burger place called ‘the burger priest’ in the town and if you like Indian the Penn Tandoori is nice.
