Success on a solo trip....make friends where you can. I solo ride plenty of times. I usually make friends on the lift, at Apres, or in the hot tub later in the eve. Ask barteners at the resort where to go for good, non-tourist happy hour. Or, ask where to snag a good tourist catch of tail. Chat people up at the bars....don't try to get them to tell you where the stash is, if you're laid-back and into just talking and show genuine enthusiam, you'll be amazed at how people love to adopt tourons. Disregard the anti-social crew here, you can ride hard from 8-4:30 and still have energy to enjoy some social interaction later in the day. However, I wouldn't suggest a 2:30 am rage on your first or second trip of the night. But the night before leaving.....it helps you sleep on the plane.
