Replying to Okemo Drinking Experts Needed for Advice!

A bunch of my friends and I will vbe going up to Okemo for the New Year's weekend.  Of the 14 of us going, only 1 is under the age of 21.  She does have a fake ID, but I was just wondering if anyone here has had any experience in finding success with a fake in the area...are the bars strict? Will she be hasseled? She looks well past 21 don't get me wrong, but it is still something that could be an issue.  Any advice from the locals? Maybe throw some names out of the more "easy going" bars?
