Not for days inn specifically, but there is a shuttle stop close by.
You can walk to the Toy Story parking lot and catch the free shuttle there.
There isn't a specific shuttle from hotel to Disneyland but it is only about a 10/15 minute walk. We had breakfast at Denny's right across the street then began our day at Disneyland.
The main carparks have a shuttle service to Disneyland. There are bus services along harbour blvd but how close they stop to Disneyland I can't say
