I think Grand Hyatt Hotel Macau did an awesome job on the idea of decorating Christmas tree this year. I was admiring on the gaint silvery-mechanic tree and start asking hotel staff about it. They told me they have been collecting all the stuff like party hats from last count down, old vases, used water bottles... from the hotel since last year. This year they wants to achieve "Upcycling Concept" into this Christmas. It's pretty amazing that they stored all the used items and recreating something modern for the Christmas.
