I never gave it a deep thought, but that could've been the reason for my whole issue @westgate. As Westgate mentioned to me after check-out, "Ms.X did show up and stayed at the resort". So, if Ms.X was in fact the original Roomer purchaser turned seller (which I never knew one way or the other), then two suites got used April 5-10. And I couldn't comprehend how in the world I got (criminally LOL) double charged, because I never knew of Ms.X; but Westgate's assumption at a later hour of April 5th check-in date could've been I'm covering Ms.X's stay!! Is this plausible, fellows?
