Are you dead set on Breck? You can get 4 packs for Keystone/A-basin for around 170. 4 days is right on the verge of break even on a season pass. I have my first trip set for 7 days in Dec. so I bought a season pass to A-basin for 300. Whatever you do I'd get on it, prices are going to go up any day now.
As far as being dead set on Breck, I've already booked a ski in/out place there. So you can say I'm dead set but we do plan to make one day out to Keystone.
The 4pack deal, could any of them days be used at Breck? I tried looking on both websites, but could not find the deal.
Any more info like this would be great!! Thanks
