I'm pretty sure that Rainforest closes the same time as AK, but if you are already in there eating, they stay open until you finish your meal-they just wont seat anyone else, this happened to us, and there was only our party, and two other parties in the entire restaraunt. They have a bus that stays there until everyone is finished, and it makes a stop at whatever resort people on the bus need to get back to, we were staying at SSR and we made stops at CBR and Pop so that was kinda cool.
