I need to book a stay of a few days at a Marriott (Renaissance) that is offering both the federal government rate and the state government rate. The fed rate offers free breakfast and free parking. The state rate offers nothing.

I work for a state entity that uses federal per diem guidelines for traveling. I've booked the federal rate at other Marriott hotels that didn't have the state rate and never been asked for federal ID. However, in this particular Renaissance hotel, the T&C for the fed rate with free breakfast and parking stimulate that an ID must be provided at check-in.

I really want the free breakfast and parking but I'm afraid when I get there that they will refuse the rate when they see the state ID. Has anyone been faced with this situation before?
