We're going to go guising when it gets dark (we start quite early as we've got a busy one), and then head down to the local Halloween event in the village! Everyone comes together and there's (hopefully!) a bonfire, mulled wine, morris dancing, costume competitions for kids and adults. Always a lovely couple of hours. Then back home for a party for the kids and their friends!
DH and I have decorated the house and made a spooky buffet (all the usual, but also colcannon as is Irish tradition, and there'll be places set at the table for those we've lost), so there'll be snap apple, duck apple, all that sort of thing. DH will play spooky tunes on the violin, the kids will generally go insane. When it all gets a bit too chaotic, the other kids will go home and we'll do spooky stories and our DC will probably crash out at around 11pm.
DH and I will collapse into bed with a glass of wine, probably still in costume, and watch a scary film.
I'd like to fit a ghost walk in there too, but doubt I'll manage it.
