Update - contacted the hotel, who advised me they see no reason why I should not have earned base points on my one night MVP rate stay. They started a case file with Honors and gave me the case #. Prior to contacting the hotel, I did a Chat two separate times inquiring about the situation, with one rep telling me "ineligible rate, sorry no points" (WRONG ANSWER), and the next rep telling me don't worry the points should be posted within 5 business days (they were not).
So frustration on many fronts....but I'll get this done.
