The answer to this depends on how long the trip is and what the accommodations are going to be. If I’m going to stay with family, I will just freeze a bunch of food and keep it on ice in a cooler - then put it right in the freezer when I get to their house. I will do the same thing if we are going to an AirBnB or a friend’s house. We usually don’t travel for more than a week or two so we can make it work. If it is going to be longer than that or we will be in a hotel or something complicated is happening like we will be camping or without power, I will transition back to dehydrated raw food (just mix it with hot water that is usually easily available) for that trip. Open Farm and Honest Kitchen are good options for this - and they pack small and light.
