Citing increased business and service demands, Resorts World Las Vegas will begin charging for valet parking at the Las Vegas Hilton, Conrad Las Vegas and South Porte Cochere locations on property, effective Wednesday.

Guests who use the hotel valet will be charged $21 per vehicle, per 24-hour period. Guests will be able to pay by credit card or room charge.

The self-parking garages will remain free to all guests, a Friday news release stated.

The $4.3 billion hotel-casino opened in late June.
