just stayed at a great hotel in LA and right next door to Disneyland.  It was the Holiday Inn Express on Walnut St. and Ball St.  And from the parking lot of the hotel you can see the fireworks show, and I mean you are right there.  Rooms are clean and good size.  There is a restaurant, which is OK, but does not stay open late, so plan accordingly. Its a bit far to walk to Disneyland, but it is do able, but since you will be walking a lot in Disneyland, suggest that you take the shuttle bus, cost about 10 bucks per person.
