I would say your chances are high, I have just done the same as a Gold.

Although Golds don't get access to the executive "Club", you might even get lucky and be upgraded to the Chambers.

Internet also doesn't work in quite the same way as other Marriotts I have stayed in, still Ibahn but it doesn't recognise the gold status. So you bill to your room and guest services said they will refund on checkout.
