I am a single mum based in london . Don’t drive. I want to take my 7yo DD on holiday this October half term to cheer her up. She is quite active. Ideally I would like to take her abroad but don’t mind a local holiday either. We have never been to a holiday park. I am a bit unsure if it’s the right place for us as single mum and DD being an only child. Would she feel lonely there? Budget is modest. £800 for two. Any recommendations?
