Can someone please PM me with the sites that Marriott honors for LNF. I've found some LNFs but before I submit I want to make sure they're "acceptable" search sites.

Tried submitting an LNF and was denied due to different cancelation policies. Comparison site was 4pm day before arrival, Marriott property was 6pm Day of arrival. Is there any way around this?

Property was Springhill Suites LAX 4/4-4/5.

Thanks!
