In some cities, parking can be as much as $46 per night (San Francisco, New York), and in some cities, breakfast can be as much as $27 per person (also San Francisco, New York, and Boston too), so a parking spot and an egg could cost as much as $73 per night/day, depending on what city the OP is talking about, and over a four day stay, that could add up to over $300 with taxes. Not exactly a minor consideration to most.
