I have a situation that this seems like the best place to ask the quetion.

I have a 5 night stay with my husband (reward) and for the middle three nights we have a room (award nights) booked of my son and daughter-in-law at the same hotel (so under my name). What nights will get credited to my account? The first reservation of five nights, the first check out (the three nights of my son and DIL) or both for 8?

I got my diamond nights qualification so this is really only for rollover but I would like it to be the 5 since the double night credit promo for that would be 10 nights and 10k points. The eight nights (so 16 credited) would be ideal but I somehow doubt that will happen.
