Had an interesting situation recently...wondering how others would react to this.

About 3 weeks ago, I completed a 1-night award stay at the Des Moines Renaissance. It was a weeknight when hotel rates were pretty high for Des Moines, and I had an award cert that was about to expire, so it made sense for that stay.

At the hotel, we were upgraded to a 1-bedroom suite. A big one - a true suite with a nice large jacuzzi, fully separate bedroom, and two bathrooms. Everything about the stay was pleasant. I assumed I'd either been given it because of elite status or because I'd provided a 25,000-point certificate for a 15,000-point hotel. Or a combination of the two...prior Gold/Plat stays at this hotel have always yielded a nice junior suite type room.

The room appeared to have been assigned to us prior to arrival. I did not have to ask the clerk whether upgrades were available.

Overnight, the normal $0.00 bill for an award stay was slid under the door. We checked out and left the hotel.

Two days later, I receive an email receipt showing a $93 charge. No explanation...it just looked like a room rate. So I called the hotel...they said "we haven't charged you anything - it's an error." I thought maybe it was one of those situations where they bill Marriott corporate $93 for an award room or something like that.

Then, last night I arrive home from a different trip and have a paper receipt, mailed to me from the hotel, stating that there was an adjustment to my account for a $56 upgrade charge. The envelope contained two papers - the $93 receipt and a $56 receipt, plus a handwritten note about the upgrade charge being $56.

However, at this time, there has been no charge to my credit card. No pending charge, no credit line hold, nothing.

So now I'm just watching my credit card account to see if a $56 charge shows up. Still crossing my fingers that this is some sort of error.

Anyone else ever had this happen?
