Looking for an app/webpage that will allow me to put in my start address, end address and varying points inbetween and it tell me the best way to go about driving there.

So far im using Google Earth, finding my places and then zooming out.

Autoroute 2007

Lol, I remember using the Dos version of that
When I was a kid and had no real place to go.

lol.  I dont use it myself but Ive seen it do exactly what your asking for.

I know a couple of companies that use it for their drivers to produce routes with multiple drop.  Seems pretty decent software.  Up to date maps, full post code, clear maos.

rac route planner?

Google maps will do it all for you m8.

Go into the "Directions" section and stick in start and destination.

Then scroll to the bottom of the directions on the left and stick another destination in.

Rinse and Repeat

You can also drag and shift entire routes on Google Maps, just drag select the blue route it has planned and reroute it via another road. Its marvellous.

I cant read maps at all

Ive always found via michelin to be the best online one.

I have google maps in my bookmark toolbar. I find that the best for long distance routes. But I need sat nav really as I can follow Go down A1 > A195  but when stopping and reading the directions and then going another little bit I find it more easy to read an A to Z.

i find googlemaps inacurate.

I normally route plan, then print a streetview from either multimap or streetmap

Its called the travelling salesman problem and has complexity of O(n!)

Not quite what Im after

I need to set off from my house, visit 3 sites, and end up back at my folks.  I want a proggie to look at where I need to go and say "you need to go here first, then here and finally here before heading to your final destination."
