"From Fishbowl (professional network used heavily by Big 4 staff): "How do I use the Acc or E&Y codes at Marriott and get around the ID check piece?" — confirming that ID checks are a well-known friction point for consulting firm codes. The thread attracted replies suggesting telling the front desk "you're a contractor doing work for them." hotelcorporatecodes.com lists EYC with 10-18% discount and verification status "⚠️ Sometimes." FlyerTalk's Marriott enforcement thread confirms consulting firms get checked more often at full-service hotels, but select-service properties rarely verify. US domestic: ~10-20% of stays checked; Europe/Asia: significantly higher."

"I mean, when I worked night audit, the whole night is practically a break after like 1am. It was usually just me and one other guy running the place (the other guy is just cleaning and doesn’t know how to do front desk). We don’t get an actual “lunch break” where we have to clock out for 30 minutes because we can’t leave the desk completely unoccupied (unless you were going to the bathroom or tension to a guest away from the desk or something). And we just ate at our desks if we were hungry, not sitting in the back."

"I have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."
