Before going to an interesting place as a tourist, get to know it.
A website or app where you can download and listen, read and view a guided pre-tour to prepare you better to enjoy the actual visit to the place.
You are visiting a large place with lots of things to see and do and would like to know the waiting line situation at all the attractions.
An app that shows you in real time where is the shortest waiting line. You can even set an alert so you get to know where you should go for a short wait.
No time commitment, use for anything.
Buy the VIP card, pre-load with money and use it for all the attractions in a given city or country, without having to make a commitment to a visit time. Just go there and use the card. You can always top it up.
Visit the places that inspired and are part of the Harry Potter world.
A game app that gives you hints on where to go. When you find such a place the app – using augmented reality – will show you facts, stories and additional “things” when you point the camera at the spot. You can collect “stuff” from places you managed to find.
