The Amado Territory Inn has been through many incarnations. It is newly remodeled and currently a Bed & Breakfast, however there is a new upscale restaurant next door. We'll have to check it out soon.
Despite its proximity to the freeway, it is a quiet respite with pleasant grounds in the rear. We have also walked their pleasant grounds, and wandered into their artist studios. It looks like a fine place to overnight and dine in the I-19 corridor when you are visiting the missions and exploring Tubac Village, Titan Missile Museum, or Madera Canyon. It is also convenient to BANWR (Buenos Aires National Wildlife Refuge) and Arivaca.
More info to come after I experience an overnight.
