Broad Hinton is a nice village with a shop, post office (how long for I wonder), a couple of pubs and a good primary school. 10 mins to Marlborough (and waitrose) with v good swimming pool and mother and baby sorts of stuff, and 20mins into the centre of Swindon.
Wootton Bassett is a market town with Tumble Tots, Music Bugs, several playgroups, 2 primary schools which are fine I understand, and a not bad secondary school. 15 mins into the middle of swindon, 10mins to the M4.
Hilmarton has a good primary school, again about 20 mins into swindon, v small village but 10 mins from Wootton Bassett with the kids stuff going on.
Wroughton is a big village/small town 10 mins from Swindon. Not sure about primary schools but the secondary school there (Ridgeway) is meant to be OK. Chisledon is popular but I don't know much about it.
The Lydiards (Lydiard Millicent etc) have the best secondary school in the area, are nicely bucolicaly rural but lots going on there in terms of groups and things, and 10 mins into swindon.
All thos are to the West/South of Swindon
I wouldn't personally live up in the Priory Vale area - have to drive everywhere, rows and rows and millions of identical boxes off the Swindon ringroad and only a gigantic Asda for excitement. If they aren't slashing prices up there in this market then they should be.
More to the east is Wanborough and Bishopstone and Ashbury - all great vibrant villages, pretty country, easy to get to the M4 (J15), 10 - 15 mins to Swindon, near the hospital, 10 - 15 mins to Marlborough. The primary school in Bishopstone is fabulous, also a v good nursery (either there or ashbury, can't remember, they are a couple of miles apart if that), good pubs, good community.
