Don't read too much into your H's behavior. I would suspect he is a bit put off that you are planning a good time. He seems to like you being at home and this trip is probably causing him to feel something he isn't accustomed to feeling.
He might not even understand what it is but it will manifest itself as an "attitude". At least that was what would happen to me sometimes.
He may be "worried" about your activities. He may show this to you when you return by asking alot of questions.
