I have been to Lake Placid many times and never had a bad experience. There are certainly all levels of skaters at both the June and August sessions, and some groups do stand around talking...however, if you work around them, or politely explain that it would be really helpful to you if they could shift a bit in one direction or another, everyone is fine with that. I have been on many dance and freestyle sessions, including ones that include the kids' camp, and the only time anyone on there had a problem was one years when a large group of high-level Italian ice dancers came onto the ice dance practice and took over the ice...you had to be bold to practice your Willow Waltz then! Being a lefty should not stop anyone from attending the camp.
