Coffee, Tea, Milk, juice are usually free, but you need to check the room service menu. Most lines have a limited room service options. Any soda or alcoholic drinks have a cost. One should always tip the person delivering room service. We usually do $2.00. My favorite room service experience is, waking up, rolling over to the phone and ordering a pot of coffee.... it's usually there within 5 minutes. Can't brew it myself that quickly. We budget $2.00 per day for morning coffee delivery.....
