If you'll be around Chandler then, honestly, you can hit up just about anywhere as you'll have freeway access nearby, and AZ Freeways are actually extremely easy to navigate to just about anywhere. As opposed to San Diego freeways which get me lost even with GPS everytime I drive there.
Anyhow... as Yoro mentioned above you're closest to the East Valley. So in terms of "nearby" the two fields to check out are:
1) Wild West Paintball:
--- They have an airball field they tend to put up on the weekends, and a recball field. Reasonable pricing. Decent amount of recball players come out.
2) Tempe Paintball
--- They're recball only, and FPO, but the perk is... they're indoors. So it's a nice place if you want to just go out and play where you can play all day without having to deal with heat, etc. I have spent quite a bit of time there. They're ALWAYS busy on Saturday/Sunday (saturday all day, Sunday earlier) so if you're without gear for a bit until yours gets here then you may want to just hit up Tempe for a time or two until it gets here so you can just play and be nearby. Once it gets here I recommend just trying as many fields as you can.
If you want to get some more serious airball/5man going on I'd recommend going out to Fort Adobve Paintball as mentioned above. It's a drive... probably about 45mins to an hour from you (I'd say most likely an hour). The thing is, though, the SWPPL is coming up in 2 weeks. It's an Arizona started, but expanding, league. Due to this teams will be out there practicing as they're the next host, and if you do some mingling I don't think you'll have any issues jumping into random games on the field. After that there's another league called the ADPL based out of Cowtown Paintball which has them busy as well.
If you have any questions feel free.
