Almost time to go home. Still unclear on process. I think the connections bus will not be running at 21.30, but does anyone know how to check? The info i see has buses stopping an hour before thst. So, to recap....if the bus is running, we should not use Nexus. If it is not running we might as well use Nexus, but then have to go through Security. It seems you are penalized for using Nexus. Thanks for any help....
