I would say online is the best - it's a little bit cheaper if you buy online about a week ahead of time. I also heard from a local if you buy the lift tickets in Denver at the supermarket you can save some money as well.
Does anyone know about lockers available at Peak 9? I'll be attending a conference at DoubleTree and will have a backpack that needs to be stowed somewhere safe before I hit the slopes. I'd love to make the transition from lecture to slopes as quick and easy as possible.
Thanks for any tips!!
