This product is a subscription to the CampingCard ACSI guide (two parts), and includes the CampingCard ACSI discount card, a mini atlas, and access to the campsite information in the CampingCard ACSI app. This will be sent to you each year. You can also use the app each calendar year. In 2020, you'll receive free access to the app. The subscription has a minimum duration of 2 years and does not stop automatically.
The discount card can be used for one calendar year. You do not have to do any administration; just fill in the back of your card completely and show it at reception. After your stay you show the card again and pay the inexpensive CampingCard ACSI rate. Any possible extra costs can be found here.
