估计，邮件说的 night 和楼主想要的 night 不是同一个范畴。邮件说的是没订房，所以没房晚。楼主要的是每年第一次会议所赠之10个房晚。
楼主可以尝试用条款 4.2.a 中的第 iv 条去 argue。
iv. When booking a qualifying group event or meeting with Marriott Bonvoy Events, ten (10) Elite nights per calendar year will be awarded to the Member for his/her first group, event or meeting, and subsequent events thereafter, one (1) Elite Night Credit will be awarded for every twenty (20) room nights booked and actualized, up to a maximum of twenty (20) Elite Night Credits per contract. Points or Miles may be earned in addition to Elite Night Credits for Marriott Bonvoy Events.
