Ask the Lounge attendent which return rail stays Airside*
Pro tip** always ask the MCO club lounge attendents which rail to take back to the main area that will keep you Airside***... There are usually 2 rails that will return you to the main, one monorail stays Airside the other rail puts you out landside for when passport control needs to be implemented for international arrivals. Many people accidentally get on the first arriving rail thinking it's going to stay Airside.
