Review for Red Garter Hotel and Casino Review For MGM National Harbor Google User Oct 10 '17 at 14:48 It was amazing! Best time is to go at night or even at dusk because that's when the place literally lights up. It has an awesome fountain 'show' in front of a projector screen that lights up with rainbow colors. So pretty! The inside is a huge casino and has other little shops and places to eat. Overall reaction - ???????? View full site to comment or like
