To have chapters, or not to have chapters... that is the question

I'm getting near the end of a novel-length work... well, the end of the first draft, at least. And it's just one long block of prose, continuous save for the odd "*" to break things up. In other words, there are no chapters... and I don't know if that is a good thing or not. Are people happy to read 85,000 words without them being broken up into chapters? I feel a quick survey coming on...
