Just back and did online check in, all rooms booked after cut off date. Here’s what happened:
2 nights all star sports, not charged, on the way in stopped at guard gate and said we were checking in then used magic band after that.
6 nights at Contemporary, not charged, on the way in stopped at guard gate and said we were checking in then used magic band after that or guard lifted the gate for us or guard scanned band.
1 night at pop, charged, on the way in stopped at guard gate and said we were checking in, never used magic band to get into resort property.
So who knows what triggered it on that last night.
