This is from the Tampa Bay Lightning's official Facebook page:
Due to increased security measures tonight, doors to Amalie Arena will open at 5:30 to allow more time for fans to enter. We are asking fans to arrive a few minutes earlier than usual and exercise patience in entering the arena. Puck drop remains 7 p.m.
Of further note, from the club's official Twitter account:
There will be a moment of silence prior to puck drop tonight to honor those affected by the events in Paris. Our hearts go out to all.— Tampa Bay Lightning (@TBLightning) November 14, 2015
It is important not just to have patience but understanding.
