Marriot room Trade / Buy

[Fenix]

I was able to book a King Size w/ a roll away in the Marriot for Thursday-Sunday, however I need a Double. Im curious if anyone would be willing to trade their double room for our King w/ roll away? If someone is able to do this please send me a PM or Reply here.

I am willing to pay money if someone is willing to help. Thanks!
