We'll be coming the beginning of October. And I'm thinking about a day trip to Sedona, but it's a surprise trip and he's the only one of us that will be old enough to rent a car (I'm still 24), so I have to wait for his input on that.
I think he'd really like TopGolf! Thanks for the idea.
See if any good concerts in the area such as at Talking Stick, or at the Musical Instruments Museum. In case he like music, the Musical Instruments Museum is amazing.
Go intertubing on the Salt River.
Do you like music? The MIM is a must do. Can be an all day event - lots to do and see.
