I stayed at the La Quinta Inn last month for a couple of months. We were on the 5th floor, in a two room suite.
I thought the room needed to be refurbished, but it sufficed for us. I would recommend it if you get a good price. They do offer a continental breakfast that includes muffins, waffles, hard boiled egg, some fruit, yogurt, bagels, donuts, coffee, juice, milk, and cereal (hot and cold).
We never used the ART, but walked, and it was fine for us.
