Re: recreational facilities, recreation center
What do you mean by "centers" or "facilities"?
To me, a center is a place you go, dedicated to recreation. Facilities can be scattered around. On campus, you may have a swimming pool in one place, a movie theater in another buidling, a bowling alley somewhere else. That gives you access to many recreational facilities, even if there is no recreational center.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
