We went to Mutiayu from the Hilton. Asked the concierge how much a taxi should be for a day. He told us 600, and then went outside and got us one for that price. He told the driver where we wanted to go, and to wait for us. Nice car, no English, but a great trip none the less. He waited for us, pointed out sights along the way (so we couldn't understand him, it was still interesting) and drove us back. Great experience.
