Per Orleans contact, the Gov of Nevada ordered casinos closed through April 30. Check your individual itinerary and contacts for verification.
My understanding of this from multiple sources is: On March 17th the Governor of Nevada ordered all non-essential businesses to close for 30 days. This included casinos. Whether the timeframe is extended remains to be seen.
I agree with this, as well. Have not seen anything showing Vegas casinos closing until April 30. This puts the 30th day on April 16th, exactly one day before the registration for the $150K Caesars BJ tournament which I am still optimistic on happening!!
