Let me try predict, because this is tough:

1. For non-elites, every two nights earns one free night up to level 4 (are then any good one's left following the recent systemwide devaluation?). Maximum is two free nights.

2. For elites, something along the lines of 25,000 bonus points for 20 nights, plus addtional 15,000 points for 5 more nights.

Wow--that took me about two days to think through. Does anyone want to bet that something wildly different will emerge from the highly-paid creative geniuses at Marriott Rewards?
