Marriott Rewards and Chase are giving 1,000 free nights this summer and all you need to do to participate is to fill out a short form.
The prize will be in the form of category 1 – 9 ecertificate that is deposited to account and must be then used within 6 months.
You can try you luck and enter here.
Note that this is only open for Marriott Rewards members in the US 50 states and DC.
The chance of winning are low but shouldn’t take more than 60 seconds of your time at most. I would probably use disposable email address because Chase will be sending out Marriott credit card ads in due course for those that participate.
