I am speaking from experience here...
When camping, I find a tin (aluminum/aluminium) or pewter cup to make the coffee cool down too quickly because of their good heat absorption. Ceramic cups are good for keeping coffee hot because they don't absorb heat as much. This is why some Formula 1 cars have ceramic engine parts. The same with plastic, Tupperware, melamine, stone and clay.
I find that a good, solid glass cup or mug keeps coffee hot for quite a lot longer than any other, especially if you can find something to cover the top and not let the steam escape. I don't mean toughened glass, that's just super Perspex, I mean real sand molten glass.
I have used a glass plunger to make espresso that has a chrome lid, a small spout for pouring that a little steam gets out from and can stay quite hot for over an hour. It holds about 3 regular cups of coffee.

To find a coffee maker that makes a single cup of coffee, check out local stores such as "Walmart" ,"Canadian Tire" and "Ikea". Stores like this will always be carrying coffee machines and most likely have single cup machines.
It makes a cup of coffee more attractive or enticing
Royal Cup

You can purchase one cup coffee makers from any manufacturer's website, which makes and sells coffee makers. I prefer black and decker, or coffeemate machines.
yes it does
A1 coffee makers can hold the most coffee for home brewers, and it makes a decent cup to boot.
KitchenAid makes a single-cup coffeemaker that is both inexpensive and works great.
Metal Cups will keep it the Warmest, for the longest amount of time.
Braun makes a 36-cup coffee maker that is still somehow considered "for home use."
