Considering the length of your stay:
Rent a car, drive up to Sedona, and spend a night up there if your appointment schedule allows it.
If not, get up early and make the drive. About 90 minutes each way. Along the way, you must stop at Cordes Junction and see Arcosanti, the futurist vision of Paolo Soleri.
Excellent suggestion for the Desert Botanical Garden and the Chihuly exhibit. Try to go there late afternoon before sunset and stay for the exhibit lighting.
Scottsdale area: Musical Instrument Museum. 4725 E Mayo Blvd, Phoenix. Many amazing exhibits from around the globe. You may not be able to make it all the way through.
Cosanti Bell Studio: 6433 E Doubletree Ranch Rd, Paradise Valley. The local sales location for Paolo Soleri's studio.
Hermosa Inn: 5532 N Palo Cristi Rd, Paradise Valley. LON's is a lovely restaurant, and beautiful boutique hotel.
Sanctuary Resort: 5700 E McDonald Dr, Paradise Valley. One of my favorite activities is a couples massage, dining on the patio, and fun in the sun beside the pool and spa. My date said it was the best three hours of foreplay she's experienced.
I've got some additional ideas, so let me know if you'd like to discuss further in detail.
