Matt Round: Using a simple form on your site you can also offer users a personalised map and directions courtesy of Google Maps. Just modify the appropriate code snippet below to include the destination and any extra formatting markup needed.
<form action="http://maps.google.com/maps" method="get">
<p><label for="saddr">Your ZIP code</label>
<input type="text" name="saddr" id="saddr" value="" />
<input type="submit" value="Go" />
<input type="hidden" name="daddr" value="[destination]" />
<input type="hidden" name="hl" value="en" /></p>
</form>
