I keep a little travel kettle in my room & a jar of coffee on a tray.
I use the mug to put the right amount of water in the kettle the night before & have a small flask I keep the milk in which keeps it cold & free from dust/flies etc..
That way I can make a nice big mug of coffee, not the little cups they seem to have on the machines & I can use any cup I want.
As there is only hot water in the kettle when I'm sat beside it boiling it to make my drink it's no problem & I have a remote to switch the socket off when I'm not using it.
I can easily bring the cup, spoon & flask etc.. down on the tray to wash it up with the other stuff & then I bring it up at night on my way to bed.
Last mothers day, for a change I brought up pain au chocolat in an airtight container & an extra flask with chilled fruit juice too.
Worked really well.
When I'm ill, I use the kettle for stuff like lemsips or cup a soups without dragging myself out of bed so it comes in really handy.
On winter nights I break out the instant hot chocolate or Malted drink & watch something like Miracle on 34th Street curled up in bed rather than having the heating on high after my son has gone to bed & if it gets cold enough I'll use it for hot water bottles without having to go downstairs.
Not every night, but quite a lot of them - means I get a good long nights sleep as well as I'll drop off if I'm tired which I wouldn't do downstairs.
My gas bill dropped by about a quarter in the cold months since I started doing that.
Added bonus is, when the (wildly overpriced) kettle in the kitchen breaks the day after the guarantee expires, the trusty little cheap travel kettle can fill in for it until I get a new (wildly overpriced) kitchen kettle.
If I ever go on holiday, I might bring it too and finally use the teeny plastic cups that came with it.
