I did my due diligence research and She got me to go all the way to the hotel for a cash service before dropping the ball that she wanted 50% downpayment to come down to the lobby to get me. Stay away from this one.
Scammer trying to hit you at the last minute when your guard is at its lowest. Good for you for walking!
Similar scam has someone approach you in the lobby pretending to be an agent or booker. They take your money and give you the (fake) room number. Some even give you a fake key card. By the time you catch on they have disappeared.
