Scottsdale Fashion Square is home to many cool and fancy stores- we happen to love Wonderspaces inside the mall. They're an art exhibit often times with interactive elements. You could easily spend well over an hour here alone!
The day after the wedding will be First Friday and downtown Phoenix has lots of events going on around Roosevelt Street. Vendors selling food, art, trinkets, lots of live music, and even restaurants and bars who will likely still be celebrating the new year!
If you've come this far, maybe you're willing to come a little further. Because Arizona is so dry, the US military stores much of their retired aircrafts here. The Pima Air & Space Museum is just south of downtown Tucson and is an amazing display of aircrafts new and old!
