It sucks to have jury duty but the jury center at the Phoenix Municipal Court was really nice and helped turn around what I thought was going to be an even crappier day. The staff were really nice and helpful. The place is built almost like a movie theater. There are about 250 seats all facing a bunch of flat panel LCDs. The facility was clean and felt brand new. On one of the flat panel TVs they display the status of the cases. So you know how many cases they have left that may need jurors. As soon as that number hits zero they say it is time to go home. It was VERY helpful to have some kind of a status indication because it lets me know something is happening. They played 3-4 movies on the other TVs. And the movies were all fairly recent. I thought the movies were going to be old ones or boring, but these were all good and a couple I hadn't seen before.
I would recommend bringing a laptop or smart phone to help keep you connected to your world while you are waiting on someone else's. They have 4 computers there that you can use.
It would be nice if they have more outlets in the general seating area. Along the wall they have seats that have plugs near them, but most of the time they are full. It would be nice if they had a hand out that provided a list of nearby restaurants. All they had was a binder and it is kinda hard to go through it when somebody else is.
On your jury summons they have a map of where to park. Be sure to bring in your parking stub to have it validated.
