This.
I often check in the day before and choose digital key. As soon as the room is ready, you get the DK notification that your room is ready. If the room was empty the night before you get the DK at 12:01PM so automatic early check in.
If you don't get the "room ready" notification, you can alway show up at the front desk and ask if there is anything available.
YMMV
