Getting a brazilian wax for the first time....? - how long does there have to be to get a bikini wax

I have a Brazilian bikini wax before going on holiday next Saturday. How long should I do? I know to do its gonna hurt like hell, but no red shock of what I wait until it disappears? In addition, take as much time to shine?
