Can I take my son to a hotel for the night without telling my husband where we are?

My husband and I have been arguing for a bit and today I have hit a point I can't be in this house and I need to think about things. He's not a bad dad but isn't around for me to maybe take a girls night to think about things, plus I don't want to be away from my son. Can I take my son, who is 4 months old, to a hotel for a night without telling my husband exactly where we are? Or is that still something I can get in trouble for? I'm not trying to start drama or any legal issues just need to breathe away from here and him. No judging please it's not like I'm trying to up and run away it's nothing like that at all.
