Any thoughts on visiting in later April? We're thinking about that time for a 4-5 night stay with some friends who've never been to an Aman.

I'm curious about day trips to Zion, Bryce, and what their daytime temps might be.

I'm also considering a flyover to Monument Valley, perhaps with a stop if that's permitted (helicopter maybe)--so any thoughts, recommendations at that time of year?

Any other random suggestions/thoughts will be appreciated. We can't wait!
