I'd put it on serving pressure, and put in in the cooler right away. When you get back on Tues., shake it every 5 - 10 minutes, until you no longer hear gas flowing when you start shaking. Then put it back in the frig until it's time to serve.
Shaking at higher than serving pressure is the best known way to over-carb a beer, and you won't have time to deal with that given your schedule. You can't over-carb shaking at serving pressure. Not shaking after Tues/Wed will give the suspended junk time to settle before serving.
Brew on
I'm leaving it on 12 psi so should be good on that front. I'm sure there's sediment in it, so good thought on giving it time to settle. Thank you!
