After a few plays, I really enjoy this game. But I find sometimes easy to make mistakes, especially when playing solo. So I wrote a small tool, in order to check the whole itinerary. It doesn't assist you too much in my opinion (but computer assistance is a matter of taste). It is not as complete as Jacek's python script, but for me, this script provides too much assistance (just my personal opinion, I fully understand why one would use this script).
