I’m confused. It sounds like there was only one night where you had two rooms booked - the night you checked your SO into the Tropicana, and then you flew to SFO and stayed in the Embassy Suites. Then the next day, you returned to LAS and checked into the WA. The entire time you were at the WA, you had no other rooms booked elsewhere.

Is that right? If so, you should still get credit for the entire WA stay, so I don’t see how you come up 4 nights short. If there were only two overlapping 1-night stays, that’s the only portion which should be in question. So I can see them saying you should have 60 nights and not 61... but I don’t understand where 57 comes from.
