I'm not sure, but there were definitely people in the GCH security line who were staying at the DLH, so maybe it's common practice for some DLH guests to use the GCH entrance? The family behind us one morning had DLH pool bracelets on. I'm not sure if it was because security opens later at the DLH, lines are longer at the DLH, or if these folks just wanted to be marginally closer to the Esplanade at 7:00 when all security opens.
