Membership can be ordered on-line and paid via bank transfer or can be purchased in person at any NGP ticket office. To become a Senior member, you must present your ID card (or any other card providing your age) at the NGP ticket office.
The membership card is non-transferable. The membership card has to be submitted, along with the valid ticket, prior to every entrance to NGP.
As of December 1 of each calendar year, NGP reserves the right, even without prior notice, to change, replace or cancel any benefit of the membership programme.
