Where to visit Santa's grotto???

[hhurt]

Ok so this year my DS will be by the time xmas comes, he's at a beautiful age where he really is beginning to understand more about Xmas,
Me and my husband are taking him to an elf workshop at cannon hall but we also want to take him to see the big man himself, we want it to be special but at the same time not stupidly priced like a lot of them are let's be honest lol....we live in Huddersfield so anyone any ideas where we can take him??
Thanks 

We're going to see Santa Underground at the National Coal Mining Museum near Wakefield. I can't wait! Under 5's aren't usually allowed on the pit tours but they are to do this. It's cost us just under £30 for 2 adults and 2 children.
