We have always found Marriott properties to have higher pet fees than most of the alternatives. It wouldn't surprise me if it's getting even worse company-wide. We were told several months ago at the Residence Inn in Colorado Springs that, due to a problem one hotel had with one pet in one room, all of the Marriott hotels in the Springs had "gotten together" and agreed to raise their pet fee. Off the top of my head, it went from $75 per stay to $150 per stay. My last stay at a Marriott in the Springs. Quite happy with other options.
