Best way to show travel time in Outlook calendar events

[Wekiva]

My office has several people who travel to local meetings quite often. In the past they've created separate events for the travel to and from the meeting which is a pain. I've learned there are add-ons for Outlook that will automatically generate travel time before and after meetings if you choose to. The one I'm looking at is made by Instyler and can be seen at http://office-watch.com/t/n.aspx?a=1473. Has anyone had experience with this or any other add-ons for outlook for travel time? I'm doing a bit of research to figure out which would be the best one for us to use. As of this time this is the only one I can find that does this.

Thanks
