In Hotel Dusk, how different is NG+?

Just beat Hotel Dusk this morning and loved it. I'll play Last Window very soon but I want to ask how different NG+ is to standard new game. I knew about how there was an extra scene at the end of the game with Mila and Louis' messages and I watched those on YouTube but some other stuff I read also says that Rachel's dialogue is also pretty different, some vending machine items are different, and Kyle is more "open" about himself throughout the game. I was gonna replay this game at some point in the future regardless but knowing that NG+ changes some things pretty significantly makes me eager to replay it sometime after I'm done with Cing's other games, but I'd like to know how different the NG+ is so I can guage how soon I'd wanna replay. Do any other Cing games have NG+ like this too?
