酒店还是厚道的，英文的member T&C 里面写着 “Lounge Membership provides access to the hotel’s Club Lounge and offered amenities within the physical space (e.g., library, meeting room, and business station)
for the registered Member plus one additional guest (the additional guest does not need to be staying at the hotel) for the duration of their stay or until time of Check-Out.”
是registered member, 不是members所以应该理解成一个房间只能register在一个客人名下，所以至多两个人。
至于保证升一级，条款就更扯淡了，认真起来酒店说从房间第二层升到第三层也算升级。。。
Room category upgrade is defined as the transition to the next-best available room type. Upgrades vary by hotel and may include but are not limited to a room on a higher floor, a room that is larger in size, has desirable views or amenities or other rooms identified as higher category by each hotel.
