I’m going to go against the majority vote and say trust your gut and don’t take him OP.
Only you know how he really might behave and it’s better to miss out on one party then to fall out with the host and party child over damage caused or by your DS doing something that might upset them or other children.
If something does happen that could have been avoided then you’ll kick yourself for not trusting your instincts and it’ll upset your DS and possibly impact any more invites to social occasions which would be frustrating when it could have been prevented.
My sister did a party at home for my niece thinking all the kids would be occupied or mostly outside in the garden and had put anything that could have been damaged in another room.
On the day most kids behaved but a couple just wouldn’t listen or join in the party and were focused on running round the house.
It wasn’t possible to keep an eye on a big group of children and the individual ones that were running riot at the same time - it was a drop and go and just my sister and two friends supervising.
They took plastic cups of Ribena through the house that got everywhere and stained bedding and furniture, a clock that was our great grandparents actually got pulled off the wall (or maybe just fell from the kids running round frantically?) and was irreparably damaged, some presents were open and damaged and the craft box (hidden in my sisters bedroom) was upended which contained scissors which caused a lot of destruction.
My sister is very house proud and had my niece young and had worked so hard and scrimped and saved to make her home lovely and was heartbroken that she couldn’t afford to replace a lot of things. A lot of my nieces things were broken which made it worse.
She was in tears when the parents came to collect the kids and shrugged off the damage and didn’t offer to replace anything.
It caused a lot of future conflict with the parents saying my sister was a drama queen and it was her own fault and some people siding with them and others with my sister.
My niece wasn’t invited to quite a few parties in the future.
If you can avoid being put in that position then why do it to yourself - even if the risk is small is it worth it?
You sound so considerate and I think it would be more appreciated if you prevent your DS from ruining the party than if he attends.
