Would love advice on a new low any stay anywhere for me! Insane! This is my new worst experience at a hotel!
As far as I can tell, the hotel gave my key to another party. Apparently, they were guests of the DC Regency Hyatt in the same number room, but the front desk didn't check ID when giving them a duplicate key to my Grand Hyatt DC Suite.
I was just awakened at 4:15am by several (20+) rings on the doorbell of my suite to find a drunk lady (drunk #1) and security guard at my door. When I open the door, the lady goes ballistic, screaming about her room with a security guard next to her. I ask what the hell is going on, ask why they are ringing the bell with the privacy sign on the door and that there are small children sleeping in the bedroom. The woman security guard, who begins to say, "I have this" isn't letting me know what the situation is. She doesn't say she is with Hyatt security, but rather tells me she is an officer, showing me her badge and handcuffs. I ask her what her name is several times - which she doesn't give me. I close the door and call down to the operator. I can hear the drunk woman yelling "you give my room to someone else!" She is soon escorted down the hall, now screaming about the "United States of Syria" and is clearly being escorted out.
While I'm on the phone with the operator - asking what the hell is going on - drunk lady #2 uses a key and bursts into the room. the operator is now screaming for security to get up there and that she will stay on the line with me. I run and bolt the door (which admittedly, I forgot to do after the first disturbance.)
After a few minutes, I make sure there is a do not disturb placed on my phone so the kids can sleep and I won't be receiving calls all morning since they thankfully slept through this entire ordeal - very nice large suite with a door between the bedroom and large living/dining room - give my cell number to the operator and let her know I'd like a call for someone by 10am the next morning letting me know what is going on, ask her to let security or whoever else is on their way not to ring the bell, but knock lightly and thank her.
Honestly, at that point, the adrenaline subsided and I had a little cry that my family was safe.
Luckily, I had enough time to make myself presentable after the cry since after 15 more minutes, I called down to ask if security or a manager was coming. After half an hour, the very young manager on duty shows up with the original security guard and not very much to say - not even an apology.(btw this means they never sent security up to my room after the operator heard a stranger break into my room!) Knowking this is going nowhere, I tell him I expect a call from the head of security and GM at 10am. The security guard is more concerned with defending herself than anything I have to say and I say goodnight to both of them after telling them how disappointed I am in the situation and their handling of it.
As I'm writing up this account, I realize that I should have the front desk change all my keys, so I'm now waiting for someone to deliver those.
Does anyone here have advice on how I should handle this, what I should expect the hotel to do?
