Thanks for the suggestion Both my wife and I are registered for all 3 promos, and we already have 3 real stays planned, but I don't know how to justify this to my dear parents who I and my children are staying with: "Mom and Dad, I will stay at an airport hotel tonight, 25 miles from your house, while the kids are with you and my wife is back home" - this may meet some resistance

The promo T&C talks about "nights", not sure how they define it but it is conceivable that checking in at 1pm and checking out at 3pm may be considered a "day" stay and disqualified.

But I see nothing in the T&C that would preclude me from staying concurrently at two brands and qualifying for both promos.

As to being back to square one with both positive and negative answers... well, I figure it doesn't hurt to ask. Yes, I am uncomfortable calling CC about this but I may actually ask on their Facebook page.

Cheers!
