Garden Wedding In Arizona

I am getting married next Oct. 2009 ((well at least thats the month we have in mind)) It might get pushed back depending on what the gardens look like then.....but....I don`t live in Arizona and that makes it very difficult to find a sight. I have been looking around and saw the Boojum Tree..The Valley Garden Center...and the Japanese friendship Garden.((all online only )) It is hard only through the internet but will be there this weekend to get a look. I would like to get some ideas from others that live in the area...like other sights...even if it is not a garden, as long as its reasonable....can anyone help me???
