Dd (just turned 10) would love to go on a riding holiday this summer, possibly with her 12 year old cousin
She's spotted some ads for places in the back of Pony magazine but I don't know anyone who's used them so would appreciate personal recommendations. She's also seen an ad for a PGL riding holiday but the advanced one is only in Wales which is a bit far in case she doesn't like it and wants to come home!
Ideally it would be somewhere where they have children from 9 or so upwards, and relatively easily accessible from London (and not too expensive ..)
