There's an effort underway in Congress to ban what are known as "resort fees." These are fees not openly disclosed when you book a hotel room and they can double the price you pay.
CBS travel expert Peter Greenberg says the practice is not new.
"It's an insidious situation that's been going on for quite some time where hotels want to be competitive on rate, but not necessarily on value, and it's not a charge that's often disclosed, and even when it is, it's not very well explained."
Greenberg says sometimes the fees are in triple digits.
"Some of these charges get really outrageous; in fact some may even exceed the cost of the room."
Greenberg says some of the worst offenders have now disclosed it on check-in forms, but they don't want you to see it.
"You have no action if you didn't ask beforehand and it was disclosed and you signed the registration form. They have now included that resort fee in their registration forms, but you need a magnifying glass to find it."
Greenberg says you've got to ask about fees when you book the room. In extreme cases the resort fee can be in the triple digits, but he says every price at a hotel is negotiable -- ahead of time.
