Sometimes booking the long stay then adjusting my check-out date at check-in helps (but I personally have ethical issues with doing this, even though I've been guilty of it in the past).

Sometimes all you can do is book a different Marriott property, or even switch to a different brand. Sorry, but I don't think there's a magic code to get around this. Just out of curiosity, why are you using LPR if you're a GOV traveler?
