[dizzymac]

We're visiting the in-laws in Stourport for the next few days. the weather is going to be vile so what can we do with a 2 DDs ( 6 and 3) please?
They love museumy type places or anywhere with a play area.

in foul weather - um - not sure. Best options are all fair weather stuff - safari park, Avoncroft, Wyre Forest. If you need fresh air no matter what then try Wyre Forest visitors centre - plus waterproofs and wellies!
