Might anyone have suggestions for my cousins with 2 young children for somewhere to go in UK for 4-6 weeks? They thought of renting in London in June or so but i fear this will be expensive and also the children need a group they can join to encourage them to speak English. I think i've heard of the National Trust running volunteer weeks but otherwise i haven't had any brainwaves for them. Their English is good by the way and children are I think 5 and 3. Thanks
