I've been through several hotel fire alarms, unfortunately none of them at 10am. At no time have any of the properties had staff to check on the vacating guests or give any direction as to where to go or how far from the building we should be. I'm only presuming someone made the rounds inside to make sure no one was still inside. None of the events were uncontained fires and most were false alarms, again no announcements made, just responses from FDCs when checking out or stopping by the front desk on the way out for the day. One CY in CA had a fire alarm going off when I pulled up to checkin. Fire trucks in the parking lot, housekeepping staff sitting on planters under the portico at the front door, alarms blaring, and no one said anything as I went in to checkin. FDC said they were trying to find someone with the key to the maintenance room to silence the alarm.
There does not seem to be any effort to tend to the guests and that's why it's very important to know how to get out of the building! YOU ARE ON YOUR OWN! I have seen some properties ask if anyone in the room would need assistance, but have never been in that situation.
