I called for TSU upgrade at HR Casablanca twice, second time day before I checked in. Both times, agent told me front desk has a note on reservation for upgrade. Since the reservation was on points, confirmed upgrades do not reflect in room description. When I checked in, front desk has no idea what I was talking about and I was assigned a Club King. I had to discuss this with the Guest Relations Manager to sort this out and I was upgraded without TSU.
For my second reservation at HR Casablanca, I sent an email request to my Hyatt Concierge and she had it done in a few days. It's irritating when calling doesn't work as it should.
