一个不少人不知道的小福利：万豪会在你生日的时候送你一个定级房晚(one elite night)。注意这个不是 Free Night，只是冲等级计算的那个晚数。
1N 看似微不足道，但或许对在漫漫保级路上的人来说，一晚能省掉很多折腾啊。
按照正常渠道，万豪应该在你生日的时候给你发一封生日祝贺邮件，在邮件里应该有一个链接，点击后就可以获得这一晚。但因为各种原因（比如和SPG混乱的合并），很多人其实并没有在生日月收到这个邮件，自然也就忽视了有这么个几乎可以免费获取的 1N。以下是 Insiders 客服回复，充分证明人人都可拿这一晚。
Hi there,
Thank you for reaching out to us here at Insiders. If you have your birthday listed in your account prior to your birthday, have elected to receive email correspondence from Marriott and partners and have had a stay in the last year, you should receive an email on or around your birthday with a link to click to receive the Elite night towards your Elite status.
If you do not receive the email in the month of your birthday and have met the criteria, please reach back out to us here at Insiders after your birthday month.
Please keep in mind that this is an Elite night not a free night.
Also, please note, we are not able to retro-actively add last year’s credit.
If your birthday has already passed this year at least 10 days ago and you have met the criteria above, please let us know when your birthday is by replying to this message from your Insiders inbox, and we’ll look into it on your behalf.
好在补登的方法也很简单，这里分享一个通过 Marriott Insiders 论坛补登的方法（Credit to FlyerTea论坛）。你也可以找客服或者大使，不过我怀疑很多客服可能弄不清楚这个东西。
步骤其实很简单：
- 注册 Marriott Insider 账号
- 提交补登申请
- 等待客服回复
第一次客服回复可能只是客套的让你确认一下没有收到生日祝贺邮件，而不是直接给你补登。这样的话你在 Insiders 里面直接再回复他们一下就好。收到 Insiders 确认补登的信息后，大概1到2天你就可以看到账户里多了一晚，多的这一晚会归类到 Bonus Night – Promotional
