Housewarming party question?

If you said no gifts, and some people didn't listen, don't embarrass the ones who did listen by opening the gifts at the party. Open them afterwards and send thank you notes.

Since there will be those who listen and don't bring gifts and those who bring gifts, it's best not to embarrass those who didn't bring by opening the gifts in front of them. So open the gifts after the party is over and all guests are gone, then send them thank you cards.

Definitely after. The only time it is acceptable for adults to open gifts at a party is when the party is a shower - bridal or baby - and the focus of the party is gift giving. For any other kind of party - housewarming, adult birthday, engagement, wedding, etc. gifts should be opened after the guests leave.

Housewarming gifts are meant to be acknowledged as each guest arrives. They are rarely wrapped but usually presented in a basket or bag or something similar. It's a very casual gift giving.

Normally you open gifts while people are still there. Everyone claps (even if its a crappy gift), do it after everyone has ate. That's what I'd say!

open them while the family members are there.

if you said no gifts then set them aside and open them later.

just say "oh, thank -you, I'll open this tomorrow"
