The best way I've found to avoid being bored is...DO Something!
You'll get a newsletter every evening with details about the next day's activities. Go to them, participate. Be active. Don't spend any time in your cabin except to change and sleep. When you feel the need to sit and read, sit in the library or game room where there is the prospect of meeting like-minded people.
I always believe it's possible to never be bored no matter what the circumstances if you adopt the mindset that life isn't boring...only some people are boring.
