We had a $600.00 ++ rate with upgrade to Mesa View Suite, with breakfast. It ended up being $ 1,000.00 a day with heavy drinking, wine at dinner and a few snacks during the day, and Prickly Pear Margaritas at the spa. Also $400++ for the Hummer Slot Canyon Tour and $ 850 ++ for the Hot Air Balloon which can only take two so no splitting the cost.

Stayed three nights and four full days. On our last day we were busy on the slot canyon tour and then came back to the resort and had lunch. We took a swim and showers in our suite and headed back to Vegas at 7PM, a very generous late check out. They did make up the suite on our last day with fresh linen on the bed and towels in the bath.Very nice!
I think three days is minimum and you could spend a week with all there is to see in the area. The resort loaned one of the BMW's to a guest we met to drive down to the Grand Canyon, they were not sure if there would be a charge for it. I'm sure in the summer more time would be spent on the Lake and all it has to offer.
