I posted this on another forum and I feel the need to post it here also. Last August, we reserved rooms for the Sturgis Rally in 2011. We were given a confirmation number saying we had the rooms reserved and everything was ok. We got an email a few days ago saying the room rates had increased almost $1000 for a 7 day stay. I didn't think that was right so I called customer service for the hotel chain and filed a complaint. I got a phone call back today saying that technically what they did was wrong. They can't increase the rates from our orignal confirmed prices. I was also told by one of the higher ups with the hotel chain that we still had our rooms at the original price and just to keep the receipts and they would reemburse us for the extra charges. By saying something, we saved almost $1000. This made me think and also the reason for this post. If this happened to us, how many others have had this same thing happen to them without them knowing it. So I would suggest that if rooms are reserved in advance beware of being over charged on your card and not catching it. Granted, this is the first time we have heard of it but I wonder how many others might have been stuck like this. We are getting our money back, have you?
