Hotel and airport question

Found out our Saturday afternoon October 29th flight on AA was canceled. No notice given but I know to check every now and then. We are now on a 6:00 am flight Sunday. How early should we arrive at the airport? Normally we do 2 hours but it seems to be overkill to show at 4:00 am. Also the condo we are staying at is already booked so need a place to stay that is quite with ac so we can get some sleep. Is Irma a place that will work for us? Not looking to spend much since we won’t be spending much time there.
