Each resort has a place to put your trash. I know at BCV there is a room on each floor that is labeled, I think it says something like trash and recycling. There is usually more trash liners on the bottom of the trash cans. It is really simple to just close up your trash and take it to the little room on the way out the building.
I am not saying you would do this, but just wanted to mention that you will see people putting trash out in the hallways for housekeeping to pick up. Please, please don't do this it makes the resort look so tacky.
