Sleepovers with all of your friends is a good start, but the party always ends splitting up into different groups. If your birthday is in the spring or summer, why not do an outdoor theme? You can buy a slip n slide and blast new music! Your parents could make burgers on the grill and u guys can just hangout in bathing suits with the hose or something! Sorry it wasnt the best advice but i hope i helped.
