if you'd bother to look at the LNF T&Cs website page
http://www.marriott.com/hotel-prices/travel.mi
you'd find out that the RC's are not (before or now) among those participating in potential LNFs........
One reservation must be made through any Marriott reservation channel (meaning our worldwide reservations centers, a Marriott hotel or an official Marriott web site) for one of the following brands: Marriott® Hotels & Resorts, JW Marriott® Hotels & Resorts, Renaissance® Hotels & Resorts, Courtyard®, AC Hotels by MarriottSM, Fairfield Inn®, SpringHill Suites®, Residence Inn®, TownePlace Suites®, Marriott® Conference Centers, Marriott Vacation Club® International, or Autograph Collection®.
