Hotels are having reservation issues

Hello, Thought I would just share where I can and say that a lot of hotels are having issues lately taking reservations over the phone, I booked 2 different hotels yesterday and haven't received confirmations for either, i'm already dealing with the issue, but the overflow hotel for anime Midwest the Chicago Marriott is unable to take any reservations over the phone, no representatives are available and you can't leave a message, so just a warning to be careful booking hotels right now!
