Divide the sections using impassable barriers such as railways and rivers,
then by main roads. The side roads of main roads are less likely to be dead
ends, so you don't even need to pass down the main road. In the worst case
there is a person either side of the main road doing something odd (noting
street signs) and they spot each other and smile/wave. It's nice to bump
into mappers, and at London  mapping parties I make a note who is doing
surrounding slices so I can keep an eye out for them.
This planning is a lot easier when you have the full road network to look at
before hand. You can identify road sections you don't need to go down.

Why don't you just man-up (or nerd-up) and go full out with getting house
numbers.

This would avoid missing name changes, and catch things like one-ways,
shops, and all the other amenities which makes OSM rich. Similar to the
London Mapping Parties. You would want to make smaller areas, but it can
also be suitable for evening mapping as smaller areas = can be closer to a
meeting point.
