Hey Kiwi, I've just had a look and many of the decent stands have already been sold.
Have a look at the map of Monaco's seating areas provided by Forumula1.com's official ticket supplier
here. You'll see some of the best seating (like area 'a2') has already sold out, but if you can get something along the pit straight, or on the swimming pool section after the tunnel (area 'e' - but consider one which has screen of the other on-track action), I think you'll still have a great day.
