After keyword searching this thread for 10 min, I have some answers and questions:

- RMPearl and Skyteam777 were able to switch from the points promo to the "stay 6" promo. But the rep told them they would track it manually and member will need to call back. Anyone switched to the promo so that it tracks and earns free nights automatically with every other stay?

- If you sign up on 3/15 (the promo registration deadline), do all your previous nights count retroactively? My travel plans might have me "stay 20 nights" or "stay 25 nights." It will be great to be able to choose the larger promo if you end up traveling more.
