Here's a response I got from the Marriott Marquis on Facebook when I asked about the "Destination Fee":
Our Daily Destination fee includes thoughtful upgrades designed to enhance your stay in New York City. The is $25 plus tax per day. The daily offerings include:
• $15 Food Credit to Fresh Bites*
• Enhanced Internet and Local/Long Distance Calls
• NYC Downtown Loop or Cruise Ticket (1 per day). See City Experts on 8th floor to redeem
• Cycle Class at CYC Fitness (1 per day). See Concierge on 8th floor to redeem
It's a total cash-grab. How is this legal?
