DH and I are headed to Scottsdale the end of Feb/early Mar. It's a business trip for him. We will stay at the Fairmont. There are activities planned for spouses during the day and dinners, etc. at night. Being a woman, the most important thing I need to know is...what to wear?!!!!!! LOL! Am I correct to expect 70's during the day and 40-50's at night? Do locals dress casually at nice restaurants (like the west coast)? Any suggestions would be greatly appreciated. I've never been there and am looking forward to it.
