Soarin' would be open the same hours as Epcot Future World except that it likely goes on until 9pm even when FW is listed as closing 7pm. The top attractions at FW like Test Track remain open until 9pm every night (later on evening EMH nights of course). Soarin' is a continuous attraction with the only gap being the time is takes to unload and load people. It is VERY popular so either get there first thing in the morning or grap Fast Passes. We saw times like 85 to 120 minutes on stand-by last month.
