@Andy3201 What's really crazy is that the menagerie of small appliances offered by the host would actually be substantially more expensive than the one you asked for. A compact electric double-burner goes for as little as $25 at Wal-Mart , Target, or Amazon.
This host sounds either dumb or lazy, and he's making this all much more of a hassle than it needs to be. But on the other hand, if all you have to do to fix the pasta problem is stop at a store and pick up one of those cheap hot plate units on the way to the home, I don't see why you would go to all the trouble of upending your travel plans over it. Sometimes you have to think on your feet instead of letting a little inconvenience erupt into a crisis, and in this situation it sounds like both the host and the guest failed to do that.
