What to ask college counselors?

Well, what exactly should I ask college counselors(or whatever it may be that they're called) when they ask me "do you have any questions?" For i.e, I'm at a college fair and I'm barely getting to the table and looking at the brochure(which has the tutition, location, majors, etc.) so, what's left to ask? I don't want to sound rude/stupid saying "Oh, no, I don't have any questions" or "I'm just looking". Thank you for your time and any feedback is greatly appreciated!
