LNF denied reason being I didn't book using the liwest available rate on the Marriott channel, but the only lower available rate is a Marriott Member rate. It doesn't make sense that they want me to compare a Marriott Member rate (non-public rate) with a public rate at a competing website!
Also, why is this thread not a sticky ? Did Marriott exert some pressure to have it unstickied, similarly to them wanting the competing OTA rates not be disclosed?
