Tlaquepaque is a beautiful venue - good choice!
A great resource for getting married in Sedona is the Sedona Wedding Professionals Association, their website is sedonaweddingpa.com (I think). Local Caterers, Photographers, Rental Company, florists, etc...
Good luck - I live in the area, so if you have any specific questions just ask!
Tlaquepaque is one of our favorite wedding locations in Sedona! It's absolutely beautiful and photographs so well.
I would also recommend the Sedona Wedding Studio as a guide for finding great information about Sedona wedding professionals.
I also live and work in the area so if anyone has questions please feel free to ask.
I've attached a pretty picture of a wedding reception at the Patio de las Companas at Tlaquepaque ... it's so beautiful there!
