11 Year Old B-Day Party

I am 11 two and am doing the same thing. What i found works in the past is finding something everyone likes. For instence, you could all go bowling or have a party at home. You could also have a scavenger hunt like a pirate party in which you could edit for age. You would give clues into where the "treasure " is hidden and it could be there party favor. You could have a pirate themed cake and everything else.
I hope you like my idea and if you dont i understand.
