How do I make everybody happy?

My fiance and i are getting married in october, and we are having a lot of trouble making everybody happy. i personally don't want an extremely religious wedding, (some is fine but not a lot). I want a wedding with a lot of black and so does my fiance, but his parents want everything to be white and pink. they also want religion to be a big part of it, even though my fiance and i don't really go for it. i want to make them happy but i don't want to have their idea of a "perfect" wedding either. i'm very afraid that they will hate me if i don't comply to their tradition and my fiance doesn't want to go against their wishes too much. also, i don't want to allow children below the age of five at my wedding because i don't want any disturbances but i don;t want to offend any of his family.
