For hot meals instead of a stove, I carry an old fashioned thermos. Pre-heat it, then put your hot water in it. My thermos has an extra cooler type sleeve it fits into. Keeps water plenty hot if everything is prepped correctly. Easier, maybe better than dealing with heating and the possible smells and off gas created.
If no service I take some books to read.
Picture books, I'm kinda simple.
