My wife and I (early 30s and in good shape) are traveling to Vegas over Easter in April of 2015. On our past visits to Vegas we have done an overnight to Grand Canyon and a day trip to Death Valley. This trip we will do a day trip to Zion. We plan to leave Vegas around 6a and hope to be back to Vegas around 7p. We want to include the Angel's Landing Hike which I am figuring will take us 4-4.5 hours. I am looking for suggestions as to how to make the best use of our remaining time (I realize that we will not have a lot after the drive and hike).
