We always stay at the DI&S and have yet to have a dirty room (and we go quite often). Their rates are always low, and the people that work there are great. There are always maintenance people walking around emptying trash cans and ashtrays or just generally cleaning something.
We also enjoy watching the fire works from their observation deck on top of the hotel at night.
Sounds like you got a parlor room ( I believe that's what it's called) californiamom. Those are nice because you can close the door between the pull out sofa area and the other area, so you and hubby can have t.v time after the little ones go to bed (or vice versa, depending on their ages

) There are TV's in each of the two sections, so it's not like you have to be all watching the same thing. You also have a fridge and microwave in the room. Their breakfast is basic toast/fruit/cereal/danishes type of thing, but, we usually either bring bagels and use their toaster (they don't mind) or just grab a danish to get us by until we're hungry later after our "morning routine".
Oh, they have free wifi too. Just call the front desk for the password as I'm not sure how often it changes and don't want to give you the wrong one. If you don't have a laptop and need to check something, there is a computer in the lobby you are welcome to use. It has a printer, so you are able to print out boarding passes or other things if needed too.
Hope that helps!
Hope you have a great trip!
