Coming from Ouray it would be a little easier and free to park in town, but more hassle to get to the Mt. Village Core from there. If you are driving up to the Mt. Village you will need to park in the parking ramp ($5). From there you take the short mini-link of the Gondola to the Village Core area. Just walk down the stairs, take a right and you'll be heading through the plaza towards the Boot Doctors. Your friends will take a left turn in the plaza and go under the bridge to the Inn at Lost Creek Hotel which houses Christy's, which is the equivalent of less than a one block walk. Once they have their stuff they can ski down to the lift, but you'll need to walk 100 yrds. back across the plaza. It's all very close, and they have maps on the T-ride web site.
If you have never been to Telluride it will undoubtedly blow your mind. It has been a thin snow year and their base sucked until last weekend when they got over 3 feet, and now it's skiing very nicely all over the mountain. Still plenty of rocks to hit it if you ski the steep stuff, so be sure and pay the couple extra bucks for base insurance on your rentals if you plan on skiing anything other than groomers.
