Trip was amazing. I will note that the own your own time is deceptively short in all locations due to travel time from "cities" to lodging. For example, in Sedona I think they gave people like 1.5 hours. We stayed longer and took an uber back ($20). It is hot, but manageable still. Like others have said, drink LOTS of water. and you won't realize how much lotion you need. But be careful as it may make you burn. Also, my lips got sunburned day 1 - that was not fun. So maybe SPF lipgloss or chapstick.
