Conclusion

The number of airlines that participate to this double airline miles offer for new members is growing (previous one only had 5).

If you are planning to join, I would probably rather take a free night certificate (read more here) or 2,000 bonus points for the first few stays (read more here).

Here are the terms and conditions of this offer:

This promotion is for new members to the Marriott Rewards program on or after July 1, 2014.
Existing Marriott Rewards members are not eligible. To see your Marriott Rewards promotions, sign into your online account.

A ‘stay’ is defined as consecutive nights spent at the same hotel, regardless of check-in/check-out activity.

Earn double bonus miles, up to a total of 35,000 bonus miles, in addition to base miles, beginning with the first stay and all subsequent stays during the promotion timeframe.
As used in these terms and conditions, “miles” means the earning currency (miles, points or other earning currency) of the airline partners participating in this promotion.
For participating airline partners whose earning currency is in kilometers, double bonus miles earned will be converted into kilometers at a conversion rate of 1.6 prior to posting to member’s preferred airline account.
Marriott Rewards base mileage earned for qualifying charges is calculated based on the airline loyalty program’s earning currency.

Stays at our exclusive luxury hotel partner, The Ritz-Carlton^®, will count toward achievement, and miles are earned on room rate only.
Miles earned based on qualifying charges that are charged to the hotel room include: room rate, meals, beverages, phone calls, movies and purchases at a Marriott-operated Gift Shop.
Non-qualifying charges are: taxes, paid outs, gift certificate redemption/gift card purchases, banquet, catering and group charges.
Members electing to earn Marriott Rewards points (“points”) are not eligible for this promotion.
Members may not earn both points and miles for the same stay.
A member may switch from earning miles to points, and vice versa, before a given stay by updating his or her membership profile.
The member will begin earning the new currency (points or miles) with the next stay after the change is made.
Previous earnings will not be converted to the new currency.
If the member wishes to “convert” points into miles, the member may redeem points for a mileage reward.
