提问有关法国迪士尼乐园Magic Ticket的问题

在官网上购票页看到，除了1天1园或2园等等的票，还有一个叫Magic Ticket的票，票价较正常的票子便宜15%，可是有限制的，但具体不是特别懂，求帮助！

以下为官网上的叙述：

- The Magic Ticket is valid :

1 day _ within a 6 months period_ from 1 day after purchase

- The Magic Ticket is valid for 1 day in the 2 Disneyland® Parks

- Valid for any attractions, shows and parades (except for the Shooting Gallery and Video Games Arcade in Disneyland® Park) for one whole day. The ticket does not entitle to attend special events or parties in the Disney® Parks.

Details

- Certain shows & attractions may be closed, modified, delayed or cancelled without prior notice, notably in the case of bad weather conditions.

- Only open to private individuals.

- The price of this special ticket cannot be further discounted.

- Please allow us 10 days for delivery if option "sent by post" selected, mailing fees apply.

- Special Tickets are non-exchangeable and non-refundable.

- Magic Ticket (which saves you 15%) not available at the entrance of both Disney Parks.

- The 15% saving is in comparison with the price of a 1-Day 2-Park Standard Ticket valid 1 year from date of purchase.
