Well, you're right and you're wrong. Just the fact that it ends with a question mark is enough to identify this as a question. But yeah, it could be also a surprised "What? You visit my aunt?!". Depends on the context.
If "czy" is used, then you can be sure that it is a real question.
If "czy" wasn't used, then we should accept the declarative word order like in your answer. Added now.
