Courtyard in Lancaster PA has a LNF opportunity. They also have a promo code for 2000 points per stay at this property. Can I use LNF and also get the bonus points, and then also choose miles as my earning pref for the 5000 delta miles?

Also while I am here, I thought marriott was min 500 miles per stay. All of my stays are only earning base miles of 1mile/$.
