The Arizona Mills mall is actually within walking distance of the Pointe Resort as well, but the streets you will walk on are very busy (you'd be walking right under 1-10 to get there), so it's almost better just to drive. Especially if you have small children or if it's still hot.
The mall has tons of stores (Burlington Coat Factory, Virgin Megastore, Hilo Hattie's to name a few), a Gameworks, a large movie theatre with 20 or so screens, as well as an IMAX movie theatre.
There are also several restaurants in the Mills or on the surrounding parking area including the Rainforest Cafe (a favorite of our daughter's, but a bit overpriced in my mind), Alcatraz Brewing Co. (a decent pub/restaurant), Claim Jumper (look out for the portion sizes at this place!!!), and the Rusty Pelican (never been).
Mills is a great place to wander around and shop for a day and then catch a movie or get some lunch/dinner.
Oh...and there's a Krispy Kreme on the far side of the mall for those of you that need your fix. :}
