I stayed and liked: Both are slightly farther away but still walkable.
Desert Palms Hotel & suites - decent free breakfast, free parking, free wifi - it's the Secret hotel on Groupon. You can see the back of carsland from the breakfast area. I liked that you only had to cross 1 street to get to the entrance but still a long walk if you have little ones. OK if you have able bodied adults.
Marriott Residence Inn Maingate on Clementine - its seems farther but still walkable. Big rooms, free breakfast, free parking, free wifi, ART picks up on site.
