Not sure if there is a cab stand at the Contemporary, but both times I needed a cab at POR and CSR, they had to call one for me and I had to wait. I'd highly recommend walking to CR and on the way there, use the Uber app to order a car. If you're not familiar with the service, google it. It's debated here on these boards, but from personal experience, I'd never take a cab again in a city that offers Uber.
