Should be a pretty time, and Dove's Rest are some great cabins. Which one? My daughter and SIL have stayed in "Fortress", and it was fantastic. You will likely see Aoudad moving into out of the canyon around dawn and dusk.
Keep in mind it's about a three mile drive from Dove's Rest to the Park entrance, and a couple of more from there to the canyon floor. On a pretty weekend, the line into the park will be very, very long.
Should be pretty, we have had some good rains, and stuff is greening up.
Set aside at least a couple of hours to tour the Panhandle Plains Museum on the WTAMU campus. It's world class.
Do a search of TexAgs, there have been a ton of threads about both places. This one on PD has some good links to other threads

https://texags.com/forums/34/topics/2502406https://texags.com/forums/34/topics/2730533One thing I've heard about Caprock Canyons is that the Bison herd has a bunch of expectant mommas. Don't know when they'll start dropping, but should be pretty cool when they do. And the mommas will be protective, so treat them like the large, aggressive, wild animals they are.
You won't need a pickup to drive anywhere, I assume you want one to carry bikes. I don't know of anyone who rents bikes in the area. I've not done a lot of business with the bike shops, but I have bought from Hills. I think Sun Adventure has the biggest inventory, followed by Hills, then Outdoor element. I have had good visits at all. So give them a call.
I've done a little hiking on the Givins-Lowery trail. It's probably a moderate trail for bikes, but one of my favorite to hike. And you'll see on my Caprock Canyons thread that I biked to the Clarity Tunnel.
Canyon Restaurants:
Sayakormarns for Asian
Pepitos for Mexican
Green Chile Willy's for Chicken Fried Steak (north of town)
Fat Boys for BBQ
Imperial Taproom for upscale
Feldman's for "American food"
Stop by Burrowing Owl Bookstore next to Sayaks
If you add Amarillo, Tacos Garcia, Tylers for BBQ (worth the trip) and Blue Sky for burgers, but only if Coyote Bluff is full.
Will reinforce the suggestion to hydrate, hydrate, hydrate.
Aggie1, no more horse stables or Sad Monkey RR in the canyon, though the Sad Monkey engine is in a park just south of the Canyon square. There is a private horse stable outside the park boundaries. I don't have any opinion on them, for or against.
