Too bad you will be missing the Tour of California by two days. The start is right next to your hotel.
Even if you like climbs, I probably would suggest 17 Mile Drive anyways. The view is incredible. Pebble Beach is a closed community. It costs something like $10 to drive in, but free for bicycles. No need to stop at the gate, just slow down and say hi to the guards. Follow the red striped line in the middle of the road. You can probably exit from the Carmel gate and venture into Carmel for a bit. Carmel Beach is also known as dog beach, so there will be tons of locals with their dogs. Avoid roads going to the Hwy-1/Morse gates. Stick the to the Pacific Grove gate to the north and Carmel date to the south.
