IMO, the majority of answers to that question are going to be the same no matter what the camp. That being said, I'm sure some folks that have been to MHSSC can give you some specific tips for that camp.
My advice: be outgoing and social with fellow campers and coaches, give the coaches lots of feedback in regards to what you want to learn, what you like skiing and such, make sure you take time to listen to everything the coaches have to say and heed their advice, ski hard, push yourself, and most of all have fun! If you're skiing hard and having fun, the rest will take care of itself.
