I don't know, I'd have thought that it wouldn't be being entertained by most, even in T1, but the shite you read on here, who knows. My friend, who I'm about out of Covid patience with, was saying about TorT & I said 'I doubt anyone will' & he said 'X wants to, he'll be so disappointed not to!'
X is 11, knows full well about Covid, but given his parents I'm not surprised he's a bit confused about what's ok & what's not frankly.
What Tier are you in? Is it permitted locally where you are? Look up the rules first - might save you the grief?
If T1 I think it will be permitted, but discouraged.
15yo who is not at all intimidating. She's tiny and more scared than scary! Is disappointed, but has worked out for herself that next to no one will want their door knocked but she's still excited to get dressed up & go fir a walk around. Done if our neighbours do incredible displays. Really amazing. So we'll all enjoy that and if any doors look inviting they might knock, but if not they'll still enjoy themselves scaring each other and looking army the decorations, then we'll have spooky fiid & watch a film or two. I have plenty of spooky sweets for them. & some individual little packets for if any do knock (won't have a pumpkin out, so not expecting any, but some of the regulars might still knock)
If you're happy for them to go, just let them go, they'll either be thrilled to price you wrong or find out the hard way. Just make it Crystal clear they're only allowed to knock at any doors that have pumpkins out.
Have the cheer up hot chocolate on the go fir when they get back!
