On the day of arrival call the front desk and ask what kind of upgrades they have available for Platinum members. If you call before the day of arrival the typical response is it's based on availability and they don't know for sure until the day of arrival. If they offer the typical "we have upgraded you to the concierge floor" response, ask to see if they have anything better. Being on the concierge floor is no big deal, you have access to the lounge anyway, what's important is the size and location of the room.

Ask for a larger room, corner room, room with a view, whatever your heart desires. If something better is available they will typically give it to you. They may give you a few types of rooms to choose from. If you are really set on getting a suite, ask for it. You'll be surprised at the response when there is availability. If they say nothing better is available, ask to speak to a front desk supervisor. They may be able to "unlock" certain rooms that a clerk cannot access. I got upgrades to Hospitality suites and Presidential suites this way. It also helps if you're a repeat or regular customer at a particular property. Get to know the management and they will take care of you. Please note this applies to the full service Marriotts, Rens, and some Courtyards. Good luck.
