I confirmed an exchange into the Sheraton Mountain Vista, but, after looking closely at the Beaver Creek trail map, I'm wondering if I should cancel it. Will the number of green runs and their length keep a beginner skier, who is not a first-timer but who doesn't like to go too fast, interested? I'm thinking the week-long vacation would include one day of lessons and three or four additional days of skiing. Also, it looks like there are sudden shifts from green runs to those that are more difficult. Have those of you who have skied there found this to be a problem? Unfortunately, it doesn't look like Vail has much to add for a beginner skier.
