Checked in at the Hilton Harbor Island in San Diego and my rate was much higher than the original reservation. I questioned it and was told the government rate was not available as it was too low. When I asked for a manager, I also pulled out a copy of my reservation and showed it to him, he finally agreed to give me the correct rate. He also stated the government rate was too low and they were losing $$ and were looking at not having that rate anymore. As a Diamond, I'd really hate to leave Hilton, but with this attitude, they are "really" not encouraging me to stay.
