ヒルトンの新しいプロモです。
登録後９０日内に４泊以上すると５００００ポイントのボーナスがもらえるという内容のようです。

Offer is valid for the recipient of this email only and is non-transferable. Members who register for the HHonors 50 Promotion by January 7, 2016 and then stay four nights within 90 days of registration will receive 50,000 HHonors Bonus Points. A ‘stay’ is defined as the total number of consecutive nights spent at the same hotel, whether or not a guest checks out and checks back in again. You must provide your HHonors account number at the time of booking. Please allow six to eight weeks from completion of your fourth night stay for Bonus Points to appear in your account. Offer is not valid for groups and cannot be combined with other select offers.
とありますからターゲット・オファーのようですが、自分が対象かどうか試してみても良いのではないでしょうか。
僕は９０日以内に４泊もするホテルはなさそうなので、登録を試していません。
