Settlers pass (with a 2 year old) - what's there?

Hi all,

Can anyone who's been to GM and done the Settlers Pass before let me know what is on offer in terms of facilities etc?

We have a 2.5 year old and have been to GM loads - once with her, last year - but never done the settler thing. We are considering it this year. I am just wondering about the practicalities with a 2 year old. So if anyone can fill me in a bit on what's available that would be great. Is there a campsite shop where you can get fresh milk/other food in the mornings or do you have to go into Crickhowell? I know there are some activities too but got the impression these were for much older children. 

If anyone can tell me a bit more about what it is like, I would be very grateful -
