If you’ve booked a night or two in Las Vegas, Miami, or Hawaii, chances are you’ve seen a “resort fee” tacked on to your bill. Often mandatory, this daily charge covers amenities such as Wi-Fi, pool access, fitness center access, and more. These fees — also referred to as destination fees, facility fees, or urban fees — typically amount to anywhere between $25 and $60 per night, and are widely despised by travelers.
