hotels.com fee nondisclosure

On 2 occasions I found that hotels.com listed a hotel as permitting pets and didn't say the hotel charged anything for pets, but, after I made my reservation and paid the charge, hotels.com then disclosed that the hotel would be imposing on me an additional charge for a pet (and didn't tell me the amount). It is fraudulent to hide mandatory charges from the consumer until after the consumer has paid. I enforced my right to the stated accommodations at the stated price by not disclosing to the hotel the presence of a pet in my room.
