Do you mean September 2014, or 2015?
If you mean 2014, then you're probably looking at where ever has spaces, which will be The Grove (near the Hospital), Lakeside and the Orchard group. Parents will probably look and sound worse. 
If you mean 2015 you'd get into any of the above. You might get into Heather Ridge, depends on the year, probably wouldn't get into Crawley Ridge but worth checking that one, used to have a catchment almost measured in cm, but I know it's less popular now as Ravenscote has come up in the world.
Windlesham infants is a long way out from Camberley, all the way down the A30 past Bagshot/Longacres, if it's where I think it is.
As Inthe says Lyndhurst is the closest, seems a fine little school, although I think it's struggling a bit recently.
Other ones inthe didn't mention are The Marist in Ascot (Catholic, but accepts any) and Hawley Place in Blackwater that's got a new head next term. Both those are girls only and go from nursery up to 16 or 18. (I think Hawley is 16, Marist is 18)
I have known a few Prior Heath parents, and I certainly wouldn't describe them as that. In fact some I'd say were positively snobby
Were they parents of current pupils or parents of prospective pupils? because that can make a difference-they may be hoping they'd get in when really they have no chance.
