I think you are going to be pressed on actually finding rates with Marriott that low. Thinking back over the past year when I was staying at a Marriott in a smaller market, it didn't equal low rates even at a Fairfield. I can't remember the last time I've paid under $100.

One thing I will share with you is if you opt to stay at only three property locations you mention and spend a considerable amount of time there, you WILL be noted on General Dynamics monthly reports. They look at each property occupancy for use of the code and after a certain period, if certain hotels continue to pop up, the company will eventually ask who is staying there.

As an example, our company uses Concur as an internal travel tool, and they match nights booked at a hotel to the nights in the system to track which employees are using the system or not as its loss rebates. Another thing is they look which properties are trending and rank each property and try to figure out why employees are staying there a lot - better hope that GD has enough need for employees in those particular markets so you don't seem like an odd line in their reports. My recommendation, don't use the code. You may get away a few times, but eventually the constant reporting will eventually show up and they will investigate if they don't ask for ID when you check in (majority of time I don't for our company code but have a few times last time). IMO you'll get away for a while but it will eventually catch up to you if you abuse at limited properties.
