My wife and I just stayed at the Loews Ventana for a job interview in the Tucson area. Everything was paid for by the job so I can't comment on some of the price related things. The area is great, definitely a resort feel. Great for couples or families. Not sure if this resort is specifically dog friendly but there were a ton of K-9's at this place. The hotel backs right up to the base of the Catalina mountains. 35 mins from the airport. It is about 15-20 mins from the University of Arizona. There is a great trail head right on the property grounds. It is a 6.2+ mile trail. My wife and I decided to do just the first 3 miles. We went in mid-November, a great time of year. Not hot and the air was cool and crisp. Great pool with the mountains hovering over you was a great atmosphere. The staff were courteous and friendly. The facilities were clean and inline with a highly rated resort.
There was a really nice golf course right on the grounds. But I'm not much of a golfer. Great restaurant called the Flying V. Breakfast was expensive for a slightly above average buffet ($$$) so you may want to investigate other options if that is important to you. Self parking was easy, convenient and free.
