I cannot IMAGINE who would pay £10.50 to see Santa, along with everything else this time of year. How are they doing any business at all???
Sorry if that isn't helpful. Although I love Christmas and go all teary seeing little 'uns when they meet a Santa, that is just greedy.
So my suggestions are these:
Do free things on the internet;
this video link was posted on another thread and it is really, really good.
elf yourself If you do a MN search I think someone posted about an improved site for this.
Ihaven't checked CBeebies website but probably seasonal fun on there
Try your local library; borrow loads of Christmassy books to read together, and there might be free Christmassy activities going on.
Is you local paper organising a free Santa? Ours did a drive round on an open topped bus draped with lights.
Have a look at local free attractions - eg museums, National TRust if you or grandparents happen to be a member - often crafty/decoration/ free things going on there.
Do an evening walk or drive round, it is dark by 5.30, to look at other people's lights on their houses.
See if you can pick up a Christmassy video from charity shop or Freecycle.
