The suits allege that the hotels’ “deceptive and misleading” pricing practices violate consumer protection laws.

The suits accuse the hotels of using the fees as a way to increase revenue without appearing to raise their room rates. Resort fee notices often are hidden in “obscure” areas, appear in smaller print, or under misleading headings suggesting they are fees imposed by local governments, the suits said.

The lawsuits seek to force the chains to advertise the true prices of their hotel rooms upfront, pay money to consumers who were harmed by the fees and pay civil penalties.
