The best feature is that it's easy to use, very intuitive interface! I have not found any dislike or problem so far with this software; however sometimes when my internet connection goes down in offline mode (due mobile data), travelboard becomes unresponsive but after some time everything gets back as normal without losing information from previous session!! Also there are many options available like "copy" option which allows me copy all important details of one city into another place by just copying those fields instead writing them again manually each day/time etc., also you can easily export your itinerary file format (.xls) at once through an excel sheet if needed later while travelling anywhere else using same computer where original was created!! This saves lota efforts especially during trips abroad!
