If you haven't held an annual pass in the 2 years prior to buying a new one, then you can be sponsored by an existing annual passholder.
This gives you 10% off the cost of your annual pass, and the existing AP holder gets a stamp towards them getting their AP extended for 12 months for free (they need 3 stamps in a designated timeframe to get the free 12 months).
You need to have the existing AP holder present, with their AP and parrainage form, with you when you buy your AP at DLP.
If you are interested in doing this, we have a designated AP sponsorship thread, where you can place your request, and if any AP holder DISboard member is going to be at DLP and can sponsor you, they will send you a pm.
If you are buying 2 Dream APs, you might be cheaper buying them through promoparcs instead, as their price is 159 euros instead of the gate price at DLP of 199 euros. You pay a little in site joining fee and postage, but I'd still expect that to be cheaper than buying 2 Dream APs with 10% sponsorship discount at the gates of DLP.
