We are older parents with an active preteen who we'd like to treat to an unforgetable themepark & beach holiday. We've both been seriously ill for some years (better now!) and our child has been through a lot. We've never been to the area before and are anxious to find somewhere neat, clean and quiet (but close enough!) to transport, shops etc. We cook, walk a lot and don't need anything too fancy or pretentious. Can you help?
