I always take pictures with people, it makes the pictures more personal to me and helps me strike up a conversation with someone who's costume I like.
My friend once said though "Why do you always have to take pictures with people? it just annoys them and they think it's weird, I can see it on their faces when you ask" which I personally think is a load of crap, since everyone I've ever asked has been super nice about it.
