Maybe the word "Top" is too strong for this list. What they really are would be best venues to find limited engagement shows. There are certainly other "Top" Venues but most of them only show the shows that they were built to show. But these are exceptions, like the Terry Fator Theater routinely has Ron White and Jay Leno but it isn't Your first guess to where they would be.
And many People do not know that if You see a show listed for Hard Rock it might be the Hard Rock Cafe on Las Vegas Blvd and not the Hard Rock on Paradise so pay close attention to that.
