Stayed in this lot for 2 nights during the summer. No one seemed to care and I was able to sleep great. Construction workers for the large resort building started showing up at 6am but no one cared.
Might be a great spot in the summer but I parked here winter time with plans to ski the following day. I got the knock early in the morning by a Stowe mountain employee. He told me they do not allow overnight parking and that no one around here does. That all being said they leave in the evening time and get in around 630am so as long as your there during those hours and move to the outside lot when they open you will be fine.
