Time Out says
We never knew Father Christmas was so fond of Dulwich, but judging by the huge team of magical helpers he's brought with him for this festive experience in a Victorian park-keepers' lodge he must think it pretty special. Visit elves bearing mulled wine, hot chocolate and mince pies. Then get stuck into a sackful of fun activities, including watching films at a log cabin cinema, listening to music in a magical yurt, decorating gingerbread biscuits with Mrs Claus and get a VIP visit with Father Christmas. The whole experience lasts an hour, and profits will help fund Whippersnappers' work delivering activities for children with disabilities.
