We were only gold when we stayed at the Don, but the person at the hotel gave us a suite upgrade when we got there. It was a room with a balcony over looking the beach, seperate sitting area and a bedroom with a King bed. I am not sure if there are other suites that qualify for the free upgreade. I would call the hotel and ask so you really know what to expect.
Geez, I got all excited thinking "That's me, That's me!!" and then I read the question. I haven't been to the Loew's in St. Pete. We did stay at Tradewinds right down the beach from it, but Don Caesar wasn't Loew's at the time. In fact, I wasn't even Loew's at the time.
