Here is a note found in my hotel room... Not going to name the name of the property or chain since I've seen similar notes at a few other hotels from different chains over the past few weeks. This is the note tonight:

To Our Valued Guest:

Over the past several months there has been an attempt by scam artists across the country to secure credit card numbers from hotel guests. These individuals will call guest rooms at random and claim to be hotel associates needing to verify credit card information. For your own protection, please do not give your credit card number over the telephone while staying in the hotel. Should you receive a call asking for this information, please hang up and contact the (front desk) immediately by dialing "0" or call the General Manager at extension ####.

We thank you for taking this necessary precaution, and please let us know if we may assist you in any way throughout your stay.

Sincerely,

General Manager

I left out the extension number since its different from hotel to hotel. In addition, I replaced the actual name of the property's front desk with (front desk) because it'll give away the name of the the brand. Just wants to give everyone a heads up.
