But it can be a bit off-putting as a fellow guest to see someone's discarded pizza crust as you're heading to breakfast.
Bethany Lambie, duty manager at one of London's most luxurious hotels, Shangri-La The Shard, London, has cleared up the etiquette.
And she tells 9Travel doing this could also prove a health risk to some guests.
While it is okay to pop your tray outside your room, she says you should really phone room service to come and fetch it as soon as they can.
"While it is common to leave trays outside, we encourage guests to call for a quick collection," she tells us.
"This ensures that the corridors remain clear and devoid of any obstruction, especially in the rare eventuality of a fire evacuation.
