Nerdfighteria! I need your help thinking of a thank-you gift!

So my friends' parents are letting me use their house for a New Years' Eve party, and I want to get them an awesome thank-you gift, but I'm completely drawing a blank! Any suggestions?

Sounds maybe a bit dull, but what about two tickets for the cinema or something like that?

Thanks guys! I think I'm either going to get them a gift card or maybe make some fudge for them. xD
