You will be completely free to use the audio guide right after the purchase, starting to listen the contents and define into details the points of interest you will see.
Using your own smartphone you'll sure that the device is sanitised : it's yours!
The app will help you to reach the point of interest thanks to maps and geo localization.
More complex points of interest for example Big Domus ( like House of deers, etc..) or spa nad gym are splitted in several sections to ensure you are always well linked to what you are watching.
