Went up with a tour bus for the Groupon $99 deal with meals.  Made the trip planned and pleasant.  We had 3 1/2 hours upon arrival - did the Skywalk which is amazing! Went to Guano Point the views are even more amazing!  There's a walk to the old aerial tram and a point you can walk up.  \nEven though you have spent $100 plus on the day - bring $100 extra in cash to shop the Hualapai artists under the tent at Guano Point.  They have beautiful things...I only had my debit card and fell in love with a pair of earrings and a ring that I couldn't buy.\nI will go again - the day was amazing.
