Sorry to hear about your lock- out
Just stopped by this property for a tour one week ago while staying across the street.Nice business center and staff
Though my favorite Hyatt property remains the The Grand Hyatt in DC based on the Regency Club and staff
These things happen.
You might let the hotel come up with a solution or perhaps suggest some GP points if that is of interest to you.
Never met a Flyertalker worth their weight who wasn't a little interested
From what I understand the hotel is going to get a renovation in the near future.
I can say that you have it pretty good overall compared with most the other area properties. With the possible exception of perhaps the Four Seasons down the road.
And even then I'm sure they too have their failures on a given day.
Welcome to another day on the road

I have heard of much worse !
Enjoy the rest of your stay.Hope it is more productive
