What time should I wake them up?

My college son who came down for the holidays
and my son who was discharged from the military ten days ago
What time should I wake them up?
Since they aren't going anywhere and are staying home
I plan to let them sleep until at least 3:00
Dakgalbi (spicy stir-fried chicken)
Pork jowl boiled meat and soup
Grilled dried yellow croaker are on standby
I checked to see if there were any Velcro strips stuck to the bed, but there aren't any
