Well you don't have to worry about seeking out the overtaking points on the circuit
I'd love to see the cars bombing it through the Swimming Pool complex (I remember seeing some fantastic twitching from the McLaren's during the TV coverage of last year's race) and also there's also the classic Loew's Hairpin (or as it's now called, the Grand Hotel Hairpin).
Perhaps the best views are from the tops of the tall buildings in Monaco - must cost a fortune to get up there though...
