Amex offer 힐튼 $13불이 부족하네요

Amex Offer 중에 

Hilton Hotels & Resorts+Curio Collection 에서 $250 이상 사용할 경우 3500MR을 준다는 게 있어서

활용하려고 했는데 하필 힐튼에서 주차비 $20을 면제해주면서(!) $13.23이 부족해서

조건을 못 채웠네요.

문제는 이게 4/15일에 expire한다는 건데.

Details 보면 

Get 3500 additional Membership Rewards points 1X by using your enrolled Card to spend a minimum of $250+ on room rate and room charges at participating Hilton or Curio properties by 4/15/17. Book direct with Hilton or Curio. See terms.

라고 되어있습니다.

체크인하는 건 말도 안되는거고 기프트 카드를 살까도 생각해봤는데

Excludes gift card purchases. Offer does not apply to advance purchase rates, including Advance Purchase, Save Now & Pay and Non-refundable rates. Corporate Cards are not eligible for this offer. Purchases may fall outside of the offer period in some cases due to a delay in merchants submitting transactions to us or if the purchase date differs from the date you made the transaction (for example, the purchase date for online orders may be the shipping date). If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the additional points. For example, your transaction will not qualify if it is not made directly with the merchant. In addition, in most cases, you may not receive the additional Membership Rewards points if your transaction is made with an electronic wallet or through a third party.

라고 되어 있네요.

현재 생각은

플랜 A. Refundable rate을 예약해놓고 나중에 캔슬해버린다.

플랜 B. 동네 Hilton에 가서 wi-fi를 결제한다.

플랜 C. 안타깝지만 그냥 포기한다.

이 정도인데 어떤 방식이 나을까요?
