interesting question.
for me, I do not carry around special coffee making equipment when I travel, mainly because I like to travel light. and sometimes I go for 3 weeks to a month at a time, so it is essential to pack very compact.
normally, I research where the great coffee shops are and what they specialize in before I visit a city. (like when I was in Hong Kong 3 weeks ago, I visited about 8 out of 17 best coffee shops in entire Hong Kong, Kind of hobby and profession of mine. I posted most of photos in this forum few weeks ago).
however, when I go to China and stay away from busy downtown, I even carry instant coffee mix, because most of coffee they serve at hotels are really undrinkable. (yes, way worse then instant drink mix)
Currently, I am in Quetzaltenango, Guatemala and at this moment, I am having a great latte from &cafe located at central park. (yes, the company name is &cafe, second largest coffee chain in Guatemala. the biggest one is called Barista cafe)
Today, I will be visiting a coffee farm in Huehue with couple of my Aussie customers and I am sure that we will be cupping some great coffee there.
Absolutely no need to take any instant mix when I come to Guatemala. One of the best coffee countries in the world.
