AAA, the American Automobile Association, is warning travelers about a scam targeting hotel guests. Scammers phone the hotel and ask for a random room number. Once connected to the guest in that room, the scammer claims to be the front desk and tells the guest there is a problem with the credit card on file. The victim is asked to provide the credit card number, ccv code, and their home address - just enough details for successful credit card fraud.
If you've checked into a hotel and receive such a call, do not provide any details to the caller. Instead, hang up and call the hotel front desk yourself to verify the veracity of the claim. AAA also advises recipients of such calls to notify hotel management.

Although it is always prudent to be cautious about giving out personal information, Snopes indicates that this warning itself may be a fraud:

Can you point to the original AAA article?
Hello,
Apparently, it’s a good old phishing ^ ^ It is true that this kind of case is fairly common … Whether online or in real life, we should never give personal information without knowing precisely the person to whom you speak.
Thank you for this article. It grows a little more caution!
Good week end.
I am the manager of a hotel. It happens all of the time. Be very careful and if you are managing a hotel, please train your staff to be careful giving out information.
