Sue, I am not sure about your question. I hope this answer will help. MSS uses daily averages during the stay. However, their mailers are based on trip. I found this out the hard way. This past fall I made several one day trips to Vegas for sports betting. Since I would have 4 -5 hours that I could gamble before leaving I went to MSS to gain some points. When my Dec Mailer came out I was only offered 2 nights and no food comps. Wow !!!. During our trip in November and I asked our host why the comps had dropped so low.
She went and checked and told us that the on day trips that I made actually hurt me and this was why the comps dropped so low. Quite honestly it is the lowest that I have seen. She told us that as always she would take care of us, but that will truly be on my daily play. We will be there next week-end.
Cheers,
