I forced a 2 day rental at the new Sheraton Waikiki location this week. Corporate phone agent said they were sold out at that location until I asked about the PC guarantee. He changed his story, called the location, and then I had a premium car for an econ rate. My daily rate was over 60% lower than they guy picking up the same car model next to me (he had reserved earlier). Very pleased with PC. Never expect the world, but they can deliver when asked.
