I'm also from AZ. We went over Thanksgiving and there was a possibility of rain so I bought us ponchos. I'll be bringing our ponchos for our trip at the end of the month. I'll bring my umbrella but I need to look for light saber umbrella! Thanks for that tip!
The lightsaber umbrellas were neat but very expensive, $65 if I remember correctly, and they couldn't keep them in stock. People were buying them as soon as they hit the shelves!
