I've had dinner at Rainforest Cafe at park closing. As we came out of the restaurant there was a CM right outside asking which resort we were going to, if we had our own car or did we need a bus, and then he directed us to a certain bus stop. At the bus stop there was another CM that again asked which resort we needed to go to. We got to talking to him and he said Disney would never leave their guests stranded and that buses would run as long as they had someone in the restaurants, no matter what time the parks closed. That bus took us back to our resort but made alot of stops along the way at other resorts.
