This is my favorite Las Vegas attraction.  Amazing!  We saw it at night and had to come back to see it during daylight.  Both spectacular.  I highly recommend this.  Free is a great value.  Brave the crowds and the sidewalk debauchery, come see this.  Bathrooms are clean.  The facility alone is worth the trip, details on the interior of the building is beautiful.  The flowers, layouts, decor and scents are a sensory feast.  Great shopping too.
