Commentary on alina's opinion:
I agree with alina. Hotels, in order to stay competitive, have to create new luxury things. The competition is tough in the luxury world. If you don't get the new amenities, others will have it before you, and the customers will pay to be in the latest, luxury hotel.
So I think that customers or groups, when they are spending time to your hotel, they have to feel like in a special place, and then tey would come back.
