Bodum measures "cups" as 4oz cups and so their 3-cup size means it holds 12oz of liquid (including what is used to brew the coffee grinds) so in reality, you get only 9 to 10-oz of actual coffee which is only a smidge more than an 8-oz US mug. For minimum 2 whole mugs of coffee, the best Bodum size is the 8-cup (32-oz) size you've got there in the stainless version. The 4-cup (16-oz) will yield just a mug and a half.

They don't make anything bigger than 16oz in their polycarb french press tumbler style but depending on how you like your coffee the tumbler has its own problems too.

I usually travel with a mini dual voltage travel kettle and either a reusable filter or some paper filter pockets so that I can make either coffee or tea. For coffee I just put the grinds in the filter, pour hot water over it and let it brew. With the reusable filter, it's very similar to french press as you get all the fragrant oils in the coffee. With the kettle, boiling water is quick and I make my coffee by the cup. If I use the room coffee maker, I make the hot water first then dunk the filter of grinds into the carafe.
