You want to travel to another country so it would be good to know all the ways you can do that.
An online software that given a departure and destination cities, and a date, will show you a table of ways to travel to that city: by train, bus, airplane, boat, etc. You can get information on travel time, cost, and other details so you can decide what’s best for you.
You want to be different and surprise your visitors while training them to behave in a particular way that is important for you.
Have a mechanism for showing popup overlays (or drop down, pull up, etc.) when the visitor has done something you wish to train them to do: stayed for a period of time, read a certain amount, clicked on individual links, etc. These pop-ups should offer something surprising while telling the visitor why, for instance: “You have been reading this article with interest – good! As a gift to you, please download this guide – free and no need to opt in.”
You are at the bus or train station and the machine selling the ticket is not very helpful.
An app that – based on your location and where you want to go – tells you what ticket to buy, how much it will cost and what to ask for when buying it at the counter, or which one to choose when purchasing at the automated ticket selling machines.
