Playing $30+3 S&G's at Party. (top 3 places pay)

It seems that every time I play in these games when it gets
down to the last 5 players it just becomes an all-in fest to
steal the blinds until players get knocked out.

My normal tight game will always get me into the top five
but I want to push for the money places and all that seems
to happen is I get dragged into coin-toss situations no
matter how I bet pre flop.

What is the best way to play this type of behaviour ?
Play certain hand groupings only ?
Use first in vigorish ?
Protect Blinds ?
Sit back and hope the others knock themselves out ?
A combination of the above ?

any advice appreciated
