Hi K.,
I have had 2 b-day parties at Desert Breeze park and honestly, the covered areas are far from the action. As another mom suggested, they have plenty of tables that are first come first serve so get out there early with your table covers, decorations, etc. and have someone maybe trade off with you on watch so you won't get too tired or bored. My suggestion would be to get there around 8:30 or 9:00am. The best location for the party would be just under the bridge which is shaded and is right in the middle of the water feature and the playground. Of course, Chuckee Cheese is nice but it gets pricey. Perhaps a friend would lend their backyard for your fiesta? At any rate, good luck and an early Happy Birthday to the little guy!
Take care,
D.
