I think there's a whole website on what you can make with the hotel room coffee maker! I just googled and there are LOTS so I'll let you peruse at your leisure.

HOWEVER, I do not like the taste of coffee--I drink hot tea instead. Whenever I used the hotel coffee maker, my tea always tasted like burnt coffee. So, I went and got myself an electric tea kettle and I take that with me when I travel. I almost always travel by car, so it doesn't matter how big it is to me. If you fly a lot, maybe a cup-sized one would work for you. Or a few cycles through the hotel CM would get the coffee taste out?

For oatmeal on the road, I mix what I like in my oatmeal (walnuts, raisins, brown sugar, and even a little powdered milk sometimes) into a ziplock bag--then I can take as much or as little as I want, knowing there's nothing artificial in it. I bring my own tea bags and raw sugar for that, too. All of that usually fits right into the kettle so it's no extra space. (I take my favorite mug--but hotel mugs are fine.) You could even set out steel cut oats to soak overnight in the hot water and they'd be ready in the morning.

You can make cup-o-soup and rice and raman noodles and all kinds of things with the hot water from the tea kettle.

The important thing is to eat right away after your work out. Happy problem solving!
