I don't use any coupon codes. I fly an entry-level turboprop, and the hotel cost is usually less than the GPU and overnight fee. I am a good steward of company money, but I have never been in a situation where I had to use one of these. I pretty much stick to Marriott properties, then Hilton as a last resort. The only time I slummed it was when I flew freight and had to stay in some Comfort and Sleep Inns, due to company restrictions.
