Divinity: Original Sin Enhanced Edition multiplayer

Is gameplay any different in Divinity: Original Sin Enhanced Edition multiplayer than in the single player game?

I was thinking of playing the game with a friend when I first got it, but I have been playing solo for a while and I cannot see how this would work in reality. There is so much to read, choices to make, places to go, etc. Playing with someone would require constant Reading things, wanting to do different things, etc. Does the gameplay change at all, or do you have to just have really good communication with your partner?
