Overseas military rates are not eligible for credit. If the stays are eligible for credit, you can include your husband on the reservation. I believe you will need to call Reservations to add the second name to your account.
Hope this helps!
First, it depends entirely on the hotel (and frankly the front desk staff). I am government employee and often book the government rate at hotels, but am often never asked for my CAC. It is a calculated risk, but one you could take. As for AndrewT, it is true that "certain" military rates are not eligible for credit, but you have to read the print carefully "
Military rates at certain overseas locations are subject to local restrictions and may be ineligible for points or elite night credit."
