If you can afford to travel from the East Coast to Arizona; I say DO IT!
This is a really good trip especially if you are not going to Nationals on a given year.
In 2003 when Arizona was a first year regional our team, 222 The TIGERTRONS, went to this regional simply because we were not eligible to attend Nationals that year. We planned this trip because we figured we would not be going to Nationals and wanted a trip to somewhere off the East Coast. We also like going to first year regionals! Instead of going to Nationals we wanted to try our best to become eligible, so that year we only planned on attending Arizona, Philadelphia, and NJ Regionals that year.
We ended up becoming eligible and went to Nationals that year anyway because of our accomplishments. However, due to our last minute travel plans we were not there to receive our Team Spirit award. Good thing we did not compete in the final matches.
If in doubt which regional to attend next year pick Arizona!
There are many things there to see and do. While we were there in 2003 we took a long bus trip to the Grand Canyon and saw fog, but we got to see many cool sights anyway! Arizona is really just a cool place to go!
If you get the chance go, go there as an educational trip as well as a sight seeing trip, you will not regret it!
GO!
