Not sure where you are but have you asked at Moreton Hall? Come to think of it it may be pricey but the actual College has some lovely grounds- may be they host Receptions to raise funding by way of income generation. The Students Union part with the pool at the back. Try them and see. Its a lovely part of Warwickshire but I'm sure there are many options.
