Scarborough child friendly site recommendation

flatcoat

We are looking for a site near Scarborough which is child friendly and has suitable facilities and 'entertainment'. This comes under the heading of hell on earth for me however we are mindful of the needs of our active 4 year old grandson's first time staying in a caravan with us. He lives normally in Moscow and only spends about 8/10 weeks a year in the UK so is in for quite an experience!
