I’ve been doing a lot of week long travel lately and I find the best way to prep is to do it all at once and then freeze the food in freezer safe bags. This gives me built in ice packs that I don’t have to bring home and keeps the food fresh and mostly still frozen when I arrive. I write on the bag what is in it portion wise and then it is all frozen when I get there. Most hotels have mini fridges in the room or you can request one. They have to give it to you or offer an alternative because of medical reasons. If you do bring ice packs they have always let me store them in the staff fridge. They will put your room number on it so when you need it you just ask. I typically call down before I head out of the room so it’s ready for me when I get downstairs.
