Parks on the Utah/Arizona border

Are there any sights or parks that I should add to this route? I’m planning a roadtrip in May of parks on the Utah/Arizona border:

  1. Valley of Fire SP A. Gunlock SP, Gunlock Falls B. Zion NP C. Bryce Canyon NP D. Arches NP E. Canyonlands NP F. Glenn NR G. Vermillion Cliffs NM, White Pocket H. Grand Canyon NP

What would you do differently with this route? Y’all were a lot of help in planning my roadtrip last year, so I’m looking forward to your suggestions
