Give me suggestion, please. I need a help!!!?

Two weeks from now, I'll get my Report, and of course my friends too. And after that, we have a plan to spend our holiday together. It's like a Farewell Party. And we don't know how to make it merry and unforgettable. So I need your idea(s) please. What will we (me and my classmates) do in our Farewell Party?
