You guys are going to have a wonderful time!!!
The Arizona Biltmore is absolutely gorgeous!!!!
Being an Arizona native, here are some hints for people on the east coast...
Bring lots of sunblock and where it whenever you are outside.

Drink lots and lots of water.
Then just have fun!!!!!!!!!!!
Just a funny thing. Our convention was here last year and all the east coast girls, especially the ones from Florida, North & South Carolina, the states full of humidity, were absolutely thrilled that their hair wasn't frizzy here. LOL. So be happy about that!
