I'm more inclined to blame this on Verizon than Marriott...but in any case, file a complaint with the FCC: https://consumercomplaints.fcc.gov/hc/en-us

Let them & their field agents bring out the monitoring equipment and figure out what really happened.

At the very least it'll stop the field agents from harassing little Mom & Pop hotels over their cable TV systems' spurious emissions, which they've been doing a lot of lately.
