In celebration of the 100th year anniversary of Holiday Park Dierenbos, a very special postage stamp series was launched. With the help of our easy to use Cee Platform the different stamps were coded with invisible Chameleon Codes. When these stamps are scanned with the Cee App, users will have access to the Dierenbos website for online bookings and a special audio clip. Not only is this an innovative way of promoting the Holiday Park, but this also provides a fun and convenient way to directly purchase tickets.
