Desert Inn & Suites has a suite that holds 10 (two bedrooms with two queen beds each and a pull out sofa in a small living room area). This room has a microwave and a small fridge and two bathrooms.
The Residence Inn Maingate (on Clementine) has suites that hold up to six. Those have full kitchens. There's a two-bedroom/two-bath suite with a queen in one room, king upstairs in a loft, and a pull out couch. They also have a kids suite with a bunk bed down stairs instead of a queen. Here they also have a hot breakfast buffet in the mornings, so with a group that size that could save you a TON of money!!
