The lawsuit claims that Marriott harmed consumers and broke the District’s consumer protection laws by not including so-called “resort fees” in the room rates advertised to consumers, particularly on online travel-booking sites such as Priceline, Expedia, and Booking.com.

Instead, the hotel company allegedly advertises a base rate for rooms to lure customers and then adds on additional fees either when the consumer ultimately books their stay or when they check out of the hotel, a practice known as “drip pricing,” the lawsuit claims. Racine said that Marriott “reaped hundreds of millions of dollars over the past decade from this deceptive drip pricing.”
