酒店設施問題 急!

You already know the answer .... No facilities is free for guest.

If you have friend stay in the hotel then you can enjoy the facilities such as 遊泳池,健身室 since you need to present the room key / card for the counter to get the locker key, towel.

You ask any free facilites of 萬麗酒店 but you have not mentioned the loaction is in Hong Kong or out of Hong Kong. You could visit the below list to have a look.

Sure you can use your friend room key /card to use the free facilities of the hotel.

Hope these information can help you.
