Msr Muddle - it's the Out of School Club close to where I live in the South Side of Glasgow.
It operates from one of the local primary schools (during term time they do pick-ups from at least two other primary schools, including ds').
I believe that there is a waiting list - at least for the after-school element, not sure about the holiday club.
It's run as a chairty (as all the adfter/out of school clubs are?), with funding/subsidy from the Council. They say they are amongst the cheapest in Glasgow - which is why they were told they "had" to put their prices up in April - from £17 to £20 a week for 3-5 days worth of after school care, and from £25 to £30 for 3-5 days of holiday club (I tihnk a single day is still £10 , but not sure). They were really apologetic too aobut putting the pirces up!
I know my SIL uses the "Mega Club", the holiday club run by the City Council at the various leisure centres.
She never managed to get her kids into the after school club at her kids' school - they have been down on the waitng list ever since beofre her ds started - and he goes to secondary school this year. Methingks someone else was abusing the system!
I, on the other hand, only rang up mid June last year, not having got my act totgether, and got ds in straight away!
