I will be taking myself, my husband, my American aunt and my two kids (ages 10 and 11) down to London in the middle of August (I live in Fife). I've never seen any gardens in that area, and I'm very keen to be able to visit at least one. If the garden in question has features that will appeal to the group, my petition will go over a lot more successfully . Which gardens would you suggest? I think we'd consider anything within an hour's train journey of the centre of London and we won't have a car.

Many thanks!
