At my rink then the rink itself has been set up with CCW in mind. The layout is such that you pay at the desk, you're walked down some stairs to the skate hire and then immediately in front of you is the public locker room. Once you've booted up then the next logical exit takes you to the closest entrance to the ice itself, which is located at the bottom of one of the long sides of the rink that, if you were to follow it (which feels like the intended direction when you get on) then you're automatically off going CCW. Cunning design...
