We checked in at 3:30 PM. Keys didn't work. Sent to another room. 90 min later a woman entered our room, no knock. What? I thought we were being ROBBED. 30 min later, a woman called our room, saying we weren't registered. (We'd registered, of course, at 3:30.) There'd been a sign that such phone calls might be scams. We refused the call. Thirty min later, sheriffs showed up at our door!!! This isn't the first time we've had a HORRENDOUS EXPERIENCE AT A HILTON. Won't stay at any Hilton property again... EVER.
