"General Dynamics is explicitly called out as high-risk: "Certain codes will automatically trigger requests — the Marriott Friends and Family and General Dynamics codes are notorious for being checked." This is one of the only non-employee codes specifically named in community lore as routinely verified on Fishbowl. Additionally, defense contractors using government-adjacent rates near military hubs like Hampton VA and Portsmouth were reported as frequently asked for ID. The combination of being specifically named as "notorious for being checked" elevates G2D to High risk."

"Corporate codes can sometimes be used for personal travel, it depends on whether: (1) your company has a negotiated rate with the specific hotel and the contract allows for personal use (2) your company has a flat percentage discount with Marriott, which typically is not subject to contractual restrictions regarding personal use. Given the rate includes breakfast, it seems like it would fall as a rate plan negotiated with the specific property. I’ve used corporate codes many times for personal travel, and am usually asked for ID for negotiated rates (particularly in Japan). With regards to your second question, when you book a flexible rate your card guarantees the reservation but no amount is taken as deposit until you arrive at the hotel (or no-show) unless the terms specifically say a deposit is to be taken."

"Corporate rate I’ve booked under for a large big tech company allows for personal use, and I’ve checked in numerous times with my family in locations where my company doesn’t have an office. I can count on one hand the number of times over the past decade (lifetime platinum) I’ve been asked for proof of employment with that company."
