Let me know if any the following are not correct

BB's can be applied only to 2 or more night stay.It can be a weekday stay.

$50 BB certs can be used at any Marriott brand hotels, but the $100 BB certs can only be used at Full service Marriotts. not sure about the $25 certs.

We cannot use more than one BB cert on a stay

If we use BB's we get stay credits and also qualify for Mega bonus when paying the balance with VISA. Since they are treated a cash

BB's can only be applied to stays paid at publicly available rates. corporate rates and AAA rates are not valid.

Priceline and other 3rd party rates are not valid for use with BB's


Sorry I looked around and could not find the answers.
