In all honesty the best way to get a suite would be to book and pay for a suite. As a gold elite you may have a tough time getting their best room if there are Plat/Plat Premiers on site, not to mention the fact that suites are explicitly kept out of the upgrade verbage for MR members.

But to answer your question this would have been an easy answer a few months ago as the GM of that hotel was my neighbor, but he has since taken over management of a hotel in Colorado so I do not know the answer to your question.

Perhaps calling the front desk at the number listed on webpage and asking for the GM would help you?
