I agree, I would think once a hotel accepted a reservation they should honor it. I would certainly continue to pursue this - but I would also talk with your company...did they not advise you that this rate was going away? maybe they can assist with Marriott, too.

However, since Monday is right around the corner.... It seems your immediate issue is finding a place to stay, and I am uncertain why you are not seeing any availability. I am finding availability at the FS. Also in closer areas than Chicago...towns as close as 30 miles or so away.

After next week, there is a good bit of availability...in several chains in all price ranges. if you truly are never going to stay at Marriott again, then you should start building a relationship with one of these.

Again, I do not think what happened is OK, and I would not let it drop - but it sounds as if this is not going to change, so you need to find a pillow for your head come Monday!

I posted several months ago that I was seeing far less corporate rate availability than at any time I could remember. I work for one of the largest corporations in the world, and our property selection has dropped by at least 50%. And in many cities- no FS at all...in some cities, no MARRIOTT properties at all - where there used to be 8 to 10 in all price ranges. We have been a Marriott corporation for years - to see this lack of relationship is astonishing to me.
