Marlene doesn't do anything related to your room upgrades.
When we checked in for our Jr Suite, we were told there were no upgrades available - we specifically asked for Club Premium. The guy at the front desk said that the Jr Suite is usually what couples get upgraded to, from either Golf Rooms or Superiors - whatever that lowest level is. So we took our Jr Suite and thought that was it.
The next day, Jeff's parents were getting in so we decided to try to front desk again since we were meeting them in the lobby. We thought that since it was Sunday a lot of people might be checking out of their CP rooms. They still told us that there was nothing available for CP but they could upgrade us to an Oceanview Jr Suite (we just had a plain old Jr Suite). They offered to send up a bellhop to help us switch rooms but we said give us 30 minutes since Jeff's parents were about to get there. When they arrived, they insisted that we take their CP Oceanfront Jr Suite. The front desk, however, could not understand this arrangement, since we still hadn't switched our original rooms and apparently this was new territory for them. So the 4 of us just switched rooms on our own without really telling the resort - his parents' names were still attached to the CP room and they had the CP bracelets, and our names were still associated with the regular Oceanview room.
About halfway through the week, Jeff's mom finally convinced Club Premium to give us bracelets so we would get all of the non-room amenities like using their CP front desk, better booze for drinks (supposedly), free Wi-fi, etc.
So, in the end, we sorta did get upgraded. But you have to take care of it on your own and it's based on availability. It was weird that they wouldn't let you just pay an extra fee per day on top of your room fee to get the bracelet. They insisted on having certain rooms set aside as Club Premium. I guess maybe it made it easier for the free room service associated with it? There was a convention going on the week of our wedding so I'm assuming why the rooms were hard to come by. Anyway, that is the story of our multiple rooms!
