So I'm taking the bar this week, and staying at a hotel for the test (3 days). I want to bring some food along with me for breakfast and lunch. I'll have a small soft-sided cooler with me, which I plan to refill with ice daily. Quick, filling, non-perishable items that can be made in a hotel room are what I'm looking for.
I'll have the regular camping staples:
I'm probably going to bring some instant oatmeal to cook in the room's coffee pot.
I'm doubtful of anything mayo-based, which nixes a lot of sandwiches, but the concept of sandwiches isn't completely off the table.
What would you bring for a 3-day, stressed-out adventure in mental endurance?
