I have been looking for an interactive tool to show my itineraries. Go Pro Travelling may be the solution. The big plus is that it uses Google Maps. The animations are fun if a bit slow. The main downside is that does not offer a wide range of flexibility. I have not figured out how to add earlier steps, tweaking the dates does not work, so once I left off the flights over to Dublin I was not going back.
The double arrows in the upper left show the steps, the play and stop buttons in the upper right control the animation. Zoom works in typical Google Maps fashion.
Readers, what do you think? Is this useful?
