有几个问题.
D airport 是抵达地还是出发地? 而且你出发地和抵达地有没有时差?
I am A. B, C, and I are newly accepted students for the fall term. We will be arriving at D airport [我默认D是抵达地了] on August 20th [请把这个换成当地时间,不能让收信人再计算你什么时候落地]. The minimum age requirement for booking a hotel is 21 years old and none of us is old enough. E told us that he will rent a car and take all of us to school on August 20th [重申,这是本地时间嘛?] You will not need to send a car to pick us up. However, due to hotel booking issue, could you possibly let us check-in to our dorms on August 20th?
