Yes on this recent trip. We got there at 10:00 AM and our room was ready and they told us to go have breakfast before we even checked in. They knew in advance that we were coming in early though so that might have made the difference when they blocked the room.
Even if your room isnt ready they will tell you to go eat something in the lounge and then check in or check in and then go to the lounge. The building is a keyed entry so just make sure you do check in before you leave the building for anything. You will need your key to get back in.
