HELP!! Keeping family at bay for birth?

Ladies, how do you feel about family being in the birth room and people taking endless pics of your baby etc? We are very private people and I am anxious about how family usually crowd you at the hospital and doesn't give you space when you go back home etc. I want privacy - not an audience. I feel that it's a special time for me and my husband, we must be the first to hold the baby, and have some time with the baby, I dont what 500 daily visitors when we go home. Its a special time for the rest of the family - I accept that, but this would be our first child (rainbow). How do you be forceful with this without offending??
