The Fabulus of Unicorns presents The House of Santa
Time Out says
Of all Santa's London hideouts, this immersive, glittery grotto in Winterville must be the most glam. A London-based troupe of dancing unicorns will be helping visitors have a memorable and magical time and Santa and his helpers will be on hand to get stuck into games, workshops and present-giving (of course). Kids of all ages are welcome to explore this sparkling wonderland, but only if they promise they've been good this year.
