My family and I stayed here several days when we could not get a place over at Las Posadas Casitas. (I've stayed solo at that other hotel and love it to death for its serenity and Spanish architecture). Doubletree is a pleasant place to relax at. But . . . for part of the time we had a smoking European girl above us (what's up with so many young people from Europe STILL smoking like it's the 1970s and everyone just found out how dangerous it is?).
We stayed in the Doubletree casitas since we were traveling with our two dogs. I would recommend staying in these, even if you don't have pets . . . our downstairs had sliding glass doors and access to an open patio and beautifully manicured lawns that meandered around . . . lovely grounds, grass, trees, birds . . . we would have missed ALL of this being in the tower. Plus, as long as you keep your dogs on leash, you can explore the grounds, lay some towels out on the grassy areas, and enjoy the smell of the grapefruit trees with their giant fruit dropped here and there. This place would be a wonderful oasis in the heat of the summer . . .
Across the street is the zoo, along with attractive Saguro cacti and Palo Verde trees in full yellow bloom. Personally, I became addicted to walking the three or so mile trail around the zoo and golf course. It is a great place to people watch, as tons of locals walk and jog around it. Lots of dog lovers have their mutts with them - but one family had an unleashed chihuahua which came right up and bit one of my dogs. Lucky for them, my other dog did not immediately react, as she would have turned that mean thing into hamburger. Shockingly, the family did not even apologize for this errant behavior. They just acted like nothing happened. So be on the lookout for unleashed dogs by some of the locals.
The absolutely breathtaking Tucson Gardens is on the same road - about two miles north of Doubletree. I had never been there & decided to visit it after much hemming and hawing (I didn't want to pay the $10 dollar entrance fee) and pouring over satellite imagery, which did not do it justice. Even though the Doubletree Hotel is on a busy road, the enchanting gardens somehow made it quiet to the point of stillness - besides an area that just highlights the cacti of the Sonoran desert & also the Chihuahuan desert, there is even a giant Saguro cacti that is the rare "curled" variety . . . something I have never ever seen . . . it doesn't even look like a Saguro. Lots of shady trees and wildflowers (and a nice spot for kids to play in, in the center).
Unfortunately, a lot of desert trails in the vicinity do not allow pets, so we had to head to the nearby Catalina Mountains for hiking. This turned out to be a good thing, as the far cooler air was much more dog friendly (it was only in the 70s down in Tucson, but cold enough up in the mountains that I had to move around just to stay warm).
I did not visit the adjacent restaurant, don't drink but saw that they have an attractive bar right inside the checkin area. Their gift shop is quite pleasant and staffed by a friendly older lady. I found that some of the staff might need some remedial training in how to make Italian visitors feel more welcome. I'm not Italian nor am I a foreigner but one young lady just did not understand how she was adding to the stress of a group of Italian travelers by her impatient demeanor and lack of understanding that if your first language is not English, one must speak s-l-o-w-l-y and gently. Having traveled around the globe, I understand that a calm, friendly tone and patient demeanor can add significantly to one's sense of happiness . . .
it can make or break a trip, especially if you are in the throes of culture shock, which they seemed to be.
In sum, I would return to Doubletree, as it is so very convenient and attractive . . . a great place to stay if you are exploring Tucson for the first time and would like to go about town on foot. My family LOVED Tucson and wants to come back every year.
