Apart from Sandy Balls . I love it there but have always stayed in their log cabins, don't really want to camp there as it looks too regimented and close together.
Most of the camp sites I have been to in the New Forest (Hollands Wood, Round Tree) are beautiful with the ponies wandering around, but I know that my kids would really miss a play area as they got used to that last year and spent most of the day there making friends.
I was looking at the Red Shoot Inn but play area looks tiny, more for tots than 7 year olds.
